Product Description

The main body of cable tower base insulator is a 95% alumina support insulator, which serves as a support for the weight of the cable tower and insulation from the ground. Its excellent compactness and excellent surface finish can effectively prevent the adsorption of dust in the air and the penetration of water vapor, and ensure the insulation performance of the product surface without flashover and creepage; higher insulation resistance, insulation resistance> 1000MΩ; Excellent mechanical properties, its pressure resistance capacity reaches 500 tons; Excellent thermal shock resistance, to ensure that there is no abnormality in its operation in the atmospheric environment. It is connected with the tower body using a spherical sliding fit, and the body of the tower is fixed and limited by the pull wires around the body.

For specific installation dimensions or special requirements, please consult the corresponding salesperson.
