Transmission line post insulators rubber boasts exceptional UV resistance, ensuring reliable performance even in outdoor conditions. Post-production, we conduct rigorous tests to ensure quality:
1. Routine tests:
Visual inspection,
Tensile load test.
2. Sample tests:
Dimension verification,
Galvanizing test,
Mechanical load test.
Only after passing these tests, insulators are packed and delivered. Trust in our quality assurance process.
Applications:
Polymeric insulator is designed for use in electrical power switches or substations with voltages up to 46 kV.
Its main function is to provide insulating support.
Competitive Advantage:
The use of first class raw materials guarantees the superior quality of our finished products.
Our prices are incomparably competitive compared to products of similar quality.
We offer OEM design services as per customer's specific needs or specifications.
