Heat Shrinkable Creepage Extender / Rain Sheds ( 3 cores )

This products are made from anti-tracking ployolefin compounds and coated with anti-track, weather resistant mastic.

Product Introduction:

Heat shrinkable creepage extender/rain sheds are made from anti-tracking ployolefin compounds and coated with anti-track, weather resistant mastic. They can provide effective protection against the flashover trouble and eliminates frequent line flashover for bushings and insulators, enhancing the high reliability  of whole power system.

The rain sheds are applied to the power cable outdoors termination in order to incresase the creepage distance and avoid the formation of sewage for various of insulators.

Characteristics:

1.Operating Temperature:-45--125 degree;

2.Shrink Temperature:110 degree;

3.Waterproof,RoHS compliant.

Standard Colors:

Red
