Composite Long Rod Insulator

Description of Composite Long Rod Insulator

Composite long rod insulator is especially suitable for use in high polluted areas and power line which of high mechanical tensile loads, large spans and compact type. Its advantage is light weight, small size, not easy to break and bending, high torsional strength, strong explosion-proof.

Feature of Composite Long Rod Insulator

1. High mechanical tensile strength. The tensile strength of the ECR core rod is 6-10 times that of the porcelain material.

2. ECR rod has good resistance to acid and other harmful gases and pollutants, it can prevent core brittle.

3. Good interchangeability.

Installation of Composite Long Rod Insulator

1. Check the composite long rod insulator before installation and use it after confirming that it is intact.

2. The rated mechanical load and rated voltage rating marked on the nameplate shall be in accordance with the line design requirements.

3. It should be placed in the packing box during transportation or store for future use. It should be handled gently to avoid collision and friction with hard, and it is prohibited to crawl or stand on composite long rod insulator.
