What is a station post insulator?

Station post (SP) insulators found in power processing equipment in power plants and substations support cables and other equipment, isolating them from the ground. SP insulators support each device; several can be connected to form an insulating column.

● Application: Fix energized conductor;

● Color: Red, Brown, Gray, or Customer's requirement;

● Applicable Standard: IEC, GB, BS, ANSI, AS, or Customer's requirement;

● Excellent mechanical and electrical properties,

●Hydrophobic properties of the silicone rubber insulation cover ensure high resistance to dirt and self-cleaning properties;

●Lower risk of mechanical damage during transport, assembly and operation;

●Resistance to UV radiation, ozone, and moisture;

●Shock and impact resistance – suitable for use in areas of seismic activity;

●Capable of carrying specific torsional loads.
