Hexagonal support insulator BI25M5 BI-25M5

Support insulator – stable busbar mounting in switchboards

This hexagonal BI25M5 support insulator is a key element for the safe and durable mounting of TH/TS busbars in switchgear cabinets. Designed for reliability, it provides solid support and insulation, minimizing the risk of short circuits and damage. It is suitable for both new installations and the modernization of existing systems.

Design and application

The BI25M5 insulator is made of high-quality plastic, which guarantees its mechanical strength and resistance to external factors. Its hexagonal shape facilitates mounting and ensures stability. Designed for use with TH/TS busbars, it is an indispensable element in the construction of safe and functional switchboards. Thanks to being made of halogen-free polyester, it is characterized by high temperature resistance – even up to 960°C – which increases safety of use.
