We can supply High-Quality ANSI Porcelain Insulator for Line Post Applications
As Supply Chain Management of medium voltage electrical equipment.We also can supply glass insulator,Fuse Cut-out
1. The insulator mainly used for fuse switches , or bus support insulations .
2. The product are with cast iron metal inserts on both end .
3. Both end of surface must be parallel very well , and the counterpart thread hole on both end must be in line. Otherwise the support insulator can't be used . In one word , there are very high requirement on insulator dimensional control .
4. On the other side , the insulator must provide very high mechanical strength . The insulator are with metal inserts on both end , so the porcelain must have higher class mechanical grade than the same product with metal caps .
