What is a strain insulator?

A strain insulator is an electrical insulator designed to work under mechanical tension (strain) to withstand the pulling force of a suspended wire or cable. They are used in overhead wires to support radio antennas and overhead power lines.

Features of strain insulator

● Application: Provide mechanical load and insulation;

● 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.
