Insulators for electrical applications

Your high-current applications primarily require mechanically resilient insulators that meet the high demands. High-quality insulators therefore play a crucial role in securing or guiding busbars.

SPS insulators are specially designed for these demanding applications. They are used wherever bare busbars need to be securely fastened, supported or guided. This ensures electrical insulation from the support system and at the same time protects against short circuits or unintentional grounding.

Properties of Insulators

Technical details

The red (support) insulators are made of glass fibre reinforced polyester with high mechanical stability and a maximum operating temperature of 130 °C. The threaded inserts on both sides are manufactured from galvanised steel. A hexagon is integrated in the centre of the insulator for fixing with a standard open-end spanner. The operating voltage is highly dependent on the height of the insulator and only reaches values corresponding to the phase voltage of 400 VAC in the case of the tall sizes. Otherwise, supports between bars of a phase, bars with earth potential or for control switchgear can be implemented easily and cost-effectively.

Features of our insulators

Whether in switchgear construction, power distribution or industrial control systems: wherever safe electrical insulation and mechanical stability are required, our SPS insulators are the ideal choice. They ensure the longevity and reliability of your high-current connections.

A key feature of our products is their high mechanical strength. We achieve this robustness by using solid insulating materials that have been specially engineered for use in industrial environments. Our insulators deliver on their promise even under difficult conditions.

In addition, we attach great importance to safety and environmental compatibility. Our SPS insulators are completely silicone- and halogen-free. This improves fire safety and minimises the risk of harmful emissions in the event of a fire. In accordance with the strict UL 94 V0 safety standard, our insulators are also self-extinguishing.
