SPS keeps a stock of selected insulators for different applications and requirements. All insulators are silicon-free, halogen-free and self-extinguishing in line with UL 94 V0. Different colors (red, black and white) have been chosen to make it easier to distinguish between the specific properties.
The red supporting insulators are made of glass fiber-reinforced polyester of high mechanical stability and with an operating temperature of max. 130°C. The threaded inserts on both sides are made of zinc plated steel. A hex for fixing with a standard OE spanner is integrated in the center of the insulator.
The operating voltage is highly dependent on the insulator height and it is only with large heights this voltage reaches high values that correspond to the phase voltage of 400 VAC. Otherwise, supporting structures can be realized between bars in a phase, bars with ground potential or for control switching systems easily and at low cost.
