Applications
DM-BB low voltage heat shrinkable breakouts are made from radiation cross linked polyolefin. The material is weather and UV resistant and has excellent electrical insulating properties which makes them widely used in the electric power industry on low voltage terminations both indoor and outdoor.
Features
Operating temperature:- 55°C to +110°C
Minimum fully recovered temperature: 130 °C
UV Resistant.
4 cores and 5 cores.
Standard color: Black.
