Anti-pollution solid-core station post insulators have characteristic of no puncture, high mechanical strength, excellent insulation and anti-pollution. This kind of insulator is safe and reliable in operation, simple in maintenance, long life in running.
Applications:
solid core station post insulator used for substations and electrical switch etc. The insulator can be used as vertical or inverted .
Features:
1. Our insulators have externally attached caps and bases. A highly engineered cementing system transfers the load uniformly from the hardware into the porcelain body.
2. Each insulator body is made from the highest quality clay raw materials that have been processed to be fully vitrified porcelain. The body is glazed to add strength to improve surface appearance, and enhance clean-ability.
3. Either chocolate brown or Munsell gray glaze is available. caps and flanges are ferrous, hot dip galvanized. thread holes are proper tapped.
Competitive Advantages:
1. The insulator core diameter are smaller ,while the mechanical strength are in high level . compare with other supplier’s product , we decrease much the unit weight .
2. we offer 3 years up to 5 years quality guarantee .
3. we will offer best competitive price to assist customer save their cost .
4. OEM design available.
