Ring Main Unit C-GIS LV Current Transformer Split Core Clamp-on Type
1. Product Introduction:
High quality epoxy resin poured into inflaming retarding PVC ring Doss hell is adopted in two half cirque metal slug and secondary windings. It has many advantages, including small size and cubage, light weight, and dispense with maintenance. It is especially fit to be fixed on the incoming/outgoing cables of the high-tension switchgear, and the two half cirque of the current transformer encircle the split phase cable tightly and uniformly. It has two configuration formats of single ratio and double ratios and two Installation modes of plastic waistband and stainless steel waistband, and it is applicable to all the 35 mm2-500mm2 and 12kV cables.
