Detail
Size specification
Introduction      
It is suitable for improving insulation and preventing short circuit of overhead wires of various voltage levels; strengthening the three-phase insulation protection of medium and high voltage lines to the transition line of the main transformer station; used for the oil switch on the column and the lead part of the urban public transformer. Easy and fast installation, built-in creepage extender, increase creepage distance and improve insulation performance. Excellent weather resistance, UV resistance and mechanical damage resistance.
