Purkeys Fleet Electric said it offers custom wiring and harness production, rather than a one-size-fits-all approach, since each application has a specific gauge and insulation requirement to ensure a safe and efficient electrical connection.
Purkeys utilizes GXL Wire from Prestolite Wire for the safest possible application (installation will not reflow). Using the latest circuit protection technology, Purkeys’ wiring harnesses provide dependable operation in the most stringent environmental conditions, the company said.
TXL, GXL, and SXL wires are all insulated with crosslink polyethylene and have heat resistance up to 125 degrees Celsius. GPT wire is insulated with PVC and is only heat resistant up to 80 degrees Celsius. According to the company, using GPT wire in the engine compartment puts vehicles at a higher risk of thermal incidents. GXL meets SAE J2549 Low Tension Primary Wire for Heavy-Duty Applications and TMC RP166(T) Low-Voltage Primary Electrical Cable Specification for Heavy-Duty Electrical Repair.
Purkeys advises to look for the following GXL wire features: thick wall design construction; excellent heat-resistant insulation; Safe Crosslink insulation that will not melt; flexible conductor stranding; high flex life; multiple packaging options; lightweight construction; lead and heavy metal free insulation; high temperature insulation rated 125C long term; high abrasion resistant insulation; high pinch resistant insulation; same physical size as GPT for easy substitution; 16x longer application life when compared to GPT @ 80C; and a universal wire solution that can be used in the engine compartment and the trailer.
Applications for Purkeys wiring harnesses include GPS systems, inverters, communications devices, remote sense alternator cables and replacement battery cables, according to the company. Purkeys added its harnesses are unobtrusive to the host vehicle and are often plug-and-play ready.
