Amphenol Industrial Global Operations offers a line of heavy-duty medium voltage couplers for hazardous electricity transfer applications in the mining, utility, tunneling, and shore power industries. Couplers vary in voltage from 600 V to 15 kV with amperages up to 600 A and feature Radsok technology for higher current ratings and mating cycles, lower contact resistance, and self-cleaning. The company’s Rapid-Couple interlock method improves mating and unmating in the field without tools or closing mechanisms. Fitting covers repel water and soil while preventing contamination, and a combined strain relief and cable system improves sealing. Couplers are constructed with standard aluminum housing and feature elongated ground planes, fully shielded phase conductors, solder and compression terminated contacts, and fire-retardant insulators.
