1. Brief introduction
PVC insulated wires belong to the series of laying electric wires, which are mainly suitable for laying at the fixed places. It is widely used as connectors of drive, lighting, electric equipments, instrument and telecommunication equipments with rated voltage 450/750Vor below. Parts of the plastic wires are used at the equipment with AC rated voltage 300/300V or below. Its working temperature is different according to different insulation materials, mainly 70 and 90 degrees temperature, etc. According to the conductor type, it includes solid conductor PVC insulated electrical wire, stranded PVC insulated wire, and flexible PVC insulated wire with different colors. According to shape, it includes flat wire, and round wire with different colors According to core number, it includes single core wire, multi-core wire with different colors.
2. Standards
The products adopt GB 5023.11997450/750V or below PVC insulated electric wires, JB 8734.15-1998450/750V or under PVC insulated cables, electric wires and flexible wires and Q/ZEL 02-2002Piastic insulated electric wires and cables. GB 5023.17-1997 is identical to IEC227, and type are same as the stipulation of IEC, technical specification is just the same, and more we have extended the range of the type to fit for the requirement of the consumers.
