Household air conditioning harness produced by Hongli Electronics are generally composed of wires, connectors, PVC sheathing, tape and other components, commonly used wires usually use standard multi-strand twisted copper wire such as UL1007 UL1015 series, insulation skin with PVC environmental insulation material. This air conditioning harness has temperature resistance, oil resistance, wear resistance, waterproof, flame retardant and other characteristics. Considering the characteristics of ac wiring harness in air conditioning, different types and high-temperature resistant wires will be selected for processing.
