Characteristics

This data sheet covers the requirements for heat shrink medium voltage breakouts whose dimension will shrink to a predetermined size upon the application of heat above 125 deg. C. Color of the MV breakouts is reddish brown. The MV breakouts are electrically insulating, anti-tracking, UV resistant, weather proof and flame retardant. MV breakouts have three fingers. The main body is internally coated with mastic and covered with a release paper.

Typical Applications

The cable breakouts provide insulation and sealing over the crutch of multi-core cables. The mastic sealant provides a water tight environmental seal to the cable. The MV cable breakouts are normally used as an integral part of 3-core cable terminations up to 36 kV.

The following application table gives the MV breakout dimensions.

S: As Supplied      R: Fully Recovered

Materials

The base material of the MV breakouts is thermally stabilized, cross linked blend of polyolefin and a compatible grade of synthetic rubber. The basic resin is mixed with chemical additives offering resistance against tracking - erosion, fire, oxidation, ozone and other environmental effects. The sealant is butyl rubber based mastic which is electrical insulating, water -proof and anti-tracking.
