Introduction | ||||
The environmentally friendly flame retardant polyolefin material can be used in 0.6~1.2kV power switch cabinets to provide insulation enhancement and protection against flashover or accidental induced discharge. Particularly suitable for switch cabinets where space is limited, it can be used for round and rectangular copper or aluminum busbars. |
