The 1.5mm² bare copper PVC insulated cable (450/750V), namely BV wire for fixed wiring, is a power transmission wire specially designed for fixed laying scenarios, widely used in low-voltage distribution systems in construction, home furnishing, industry and other fields. Its core conductor is made of high-purity bare copper with a purity of more than 99.95%, which has excellent electrical conductivity, can effectively reduce energy loss during current transmission, and ensure the stability and efficiency of power transmission.​ In terms of specification parameters, the cross-sectional size of the cable is 1.5mm², and the rated voltage is 450/750V, which is suitable for fixed laying environments with an AC rated voltage of 450V and below, as well as specific fixed connection scenarios below 750V. In terms of current-carrying capacity, at an ambient temperature of 30℃, its current-carrying capacity is about 14-20A, which can meet the power supply needs of household lighting and small household appliances (such as table lamps, chargers, TVs, etc.), and is also suitable for lighting circuits and ordinary socket circuits in office buildings, shopping malls and other places. This current-carrying capacity is obtained through strict testing. In actual use, if the laying environment temperature rises or pipe conduit installation and other laying methods that affect heat dissipation are adopted, the current-carrying capacity needs to be appropriately reduced to avoid safety hazards caused by overheating of the cable.​ The insulation layer of the cable is made of polyvinyl chloride (PVC) material, which has good electrical insulation performance, chemical corrosion resistance and mechanical strength. The thickness of the insulation layer is uniform, generally between 0.6-0.8mm, which can effectively isolate the conductor from the external environment and prevent faults such as electric leakage and short circuit. At the same time, the PVC insulation layer has a certain degree of flame retardancy, which is not easy to burn quickly when exposed to open fire, and can delay the spread of fire, gaining time for personnel evacuation and fire fighting. In addition, this material also has good aging resistance, which can ensure the long-term stable operation of the cable under normal use conditions.​ In terms of applicable scenarios, the 1.5mm² BV wire is mainly used for fixed wiring, such as concealed laying in building walls, pipe laying in ceilings, trunking laying, etc. In home decoration, it is often used for lighting lines and ordinary socket lines in living rooms, bedrooms, kitchens and other areas; in commercial places, such as offices, supermarkets, restaurants, etc., it can be used as power supply lines for lighting and small electrical equipment; in the industrial field, it is suitable for fixed power connection and control circuit wiring of small equipment. Its fixed laying characteristic determines that it is not suitable for scenarios with frequent movement or bending, but more suitable for long-term stable power transmission.​ In terms of material and structure, the conductor is a single-strand bare copper, with a solid structure, not easy to break, and convenient for cutting and connecting during construction. The insulation layer is tightly wrapped around the conductor, firmly combined with the conductor, without defects such as bubbles and wrinkles, and can effectively resist external mechanical damage and environmental erosion. The overall structure of the cable is stable, and can withstand a certain amount of tension and pressure during laying, ensuring good performance in long-term use.​ In terms of production process, the cable is manufactured through strict processes. First, high-purity copper is made into 1.5mm² single-strand bare copper conductor through smelting, wire drawing and other processes to ensure uniform diameter and smooth surface of the conductor. Then, the extrusion molding process is used to wrap the PVC insulation layer around the conductor. By precisely controlling the extrusion temperature, speed and pressure, the thickness of the insulation layer is uniform and the quality is stable. During the production process, each batch of products undergoes a number of tests, including tests on conductor resistance, insulation resistance, voltage withstand strength, insulation thickness and other indicators, to ensure compliance with relevant standards such as GB/T 5023-2008 "Polyvinyl chloride insulated cables with rated voltage up to 450/750V".​ During installation and use, the specifications and requirements of fixed wiring must be followed. During laying, excessive bending, extrusion or pulling of the cable should be avoided to prevent damage to the insulation layer. The joints need to be strictly processed, using special terminals or connectors, and good insulation sealing should be done to prevent moisture, dust, etc. from entering and affecting the cable performance. At the same time, it is necessary to ensure that the laying environment of the cable is dry and ventilated, away from harmful factors such as high temperature and corrosive substances.​ To sum up, the 1.5mm² bare copper PVC insulated cable (450/750V) BV wire for fixed wiring, with its excellent electrical conductivity, reliable insulation protection, stable structure and wide applicability, has become an indispensable power transmission wire in fixed laying scenarios, providing safe and efficient power support for low-voltage distribution systems of various buildings and facilities.

This greatly simplifies construction processes such as wall conduit threading and ceiling wiring, reducing installation complexity and labor costs. The overall rated voltage of the cable meets the requirements of low-voltage power distribution systems (usually 450/750V), among which 450V is the normal working voltage, compatible with the 220V single-phase power supply network of residences, and the 750V insulation withstand voltage value provides an additional safety margin. It can resist electrical stress caused by voltage fluctuations and avoid the risk of insulation breakdown. In addition, the 100m roll specification is suitable for the wiring dosage needs of residences. It can meet the partial or overall wiring of small and medium-sized residences (such as two-bedroom and three-bedroom houses), and is convenient for cutting according to needs, reducing cable splicing and the risk of joint faults. At the same time, the roll design is conducive to storage and transportation, preventing the cable from being knotted or damaged during construction.​ In terms of material and structural design, the cable uses high-purity solid copper (purity ≥99.95%) as the conductor core. Solid copper material has three core advantages: First, it has excellent electrical conductivity with extremely low resistivity (about 1.72×10⁻⁸Ω·m), resulting in little energy loss during current transmission. It can reduce electricity waste in long-term use and at the same time reduce conductor heating, avoiding insulation aging caused by overheating.

Third, it has strong corrosion resistance, and its surface is not easy to oxidize, so it can be used for a long time in humid residential environments (such as kitchens and bathrooms), extending the service life of the cable. The insulation layer is made of flame-retardant PVC material, which has good electrical insulation, temperature resistance, and flame retardancy: Electrical insulation can effectively isolate the current conduction between conductors and between conductors and the outside world, preventing short circuits or electric leakage. Temperature resistance ensures that the cable works stably in an environment of -30°C to 70°C, adapting to temperature changes in different areas of the residence (such as stuffy ceilings in summer and cold balconies in winter). Flame retardancy complies with relevant national standards, and it can self-extinguish when exposed to fire, avoiding the spread of flames and adding a guarantee for residential electricity safety.​ In terms of application scenarios, relying on the advantages of 3-core integration and 2.5mm² specification, this cable fully covers the needs of house wiring and small electrical installation. In new houses, it can be used as the main wiring for lighting and ordinary sockets in living rooms and bedrooms. The three cores correspond to the live wire, neutral wire, and ground wire respectively, meeting the safe electricity use specifications. In areas such as kitchens and bathrooms, it can be used to connect the power supply circuits of small and medium-sized household appliances (such as dishwashers and electric water heaters). The combination of solid copper conductors and flame-retardant PVC can cope with humid and high-temperature environments. In old house renovations, it can directly replace old cables. Through the 3-core design, the number of wall grooves is reduced, and damage to the original decoration is minimized. In addition, this cable is also suitable for electrical installation in small commercial spaces (such as convenience stores and small offices) as the power supply line for lighting and cash register equipment. The 100m roll can flexibly adapt to the wiring length needs of different spaces.​ In terms of construction and safety characteristics, the solid copper conductor of the cable is easy to strip and wire, compatible with common terminals, sockets, and switches. Installation can be completed without special tools, improving construction efficiency. The 3-core parallel arrangement structure is not easy to entangle when threading through conduits, and can easily pass through narrow wall pipes or ceiling gaps. The surface of the insulation layer is smooth, with little friction with the inner wall of the conduit, reducing the resistance of threading. In terms of safety, in addition to flame retardancy and insulation performance, the cable also passes strict quality inspections (such as conductor resistance test, insulation withstand voltage test, and flame retardant test) to ensure compliance with national electrical safety standards. During use, problems such as insulation aging and conductor breakage are not easy to occur, providing long-term and reliable protection for the residential electrical system.
