What Are The Requirements For Installation Of Suspension Insulators?

The installation of composite tension insulator should meet the following requirements:

1. Except for design reasons, high voltage transmission line insulators should be vertical to the ground. When the conditions cannot meet the requirements, there can be an inclination angle of no more than 5°.

2. When overhead power line insulators is connected in parallel, the tension of each string should be uniform.

3. When tension insulator is combined, the bolts, pins and locking pins of the connecting hardware must comply with the current national standards and should be complete. Their penetration direction should be consistent. The bowl of the tension insulator string should be upward, and the ball head hanging ring, bowl head hanging plate and locking pin of the insulator string should match each other.

4. The spring pin should have sufficient elasticity, the closed pin must be separated, and there must be no breakage or cracks. It is strictly forbidden to replace it with wire.

5. The protective hardware such as the equalizing ring and the shielding ring should be installed firmly and the position should be correct.

6. The insulator string should be cleaned before hoisting.
