Insulation products with excellent corrosion resistance,weather resistance.Good flame retardant, soft and flexible.
0.6/1KV heat shrinkable busbar protection sleeve MPG-1: a kind of good insulation, flame resistance and resistance to aging of the heat shrinkable tube, widely used in high voltage switchgear, substation busbars insulation protection could serve to prevent short circuit of small animals to prevent the maintenance personnel strayed into electrically charged space, to prevent condensation flashover, increased white insulation, effectively reduce the busbars to the distance between white and extend the life of bus row.
