Application insulators

SPS insulators are used where bare high-current connectors such as copper busbars have to be attached, carried or routed.

Our insulators have a high mechanical load capacity and are made of solid insulating materials.

SPS insulators are silicone and halogen-free as well as self-extinguishing in accordance with UL 94 V0.

Assembly & processing of the insulators

The red post insulators are made of glass fiber reinforced polyester with high mechanical stability and an operating temperature of max. 130 °C.

The threaded inserts on both sides are made of galvanized steel. A hexagon is integrated in the middle of the insulator for fixing with a common open-end wrench. The operating voltage heavily depends on the height of the insulator and only reaches values ​​corresponding to phase voltage of 400 VAC for larger sizes. Otherwise supports between busbars of a phase, busbars with earth potential or for control switchgear can be implemented easily and inexpensively.
