Silicone rubber coating application
High performance coatings are used preserve and protect a multitude of different materials including masonry,ceramic,metals,plastics and wood.
Advantage of composite insulator
Polymeric composite insulators Offer significant advantages over porcelain and glass insulators especially for ultra HV transmission lines.
The specific advantages of composite insulator, compared with ceramic insulators are:
Light weight,and lower construction and transportation costs.
VandaIism resistance,less gun shot damage.
High strength to weight radio longer span/new tower.
Better contamination performance.
lmproved transmission line aesthetics．
Hydrophobicity Of insulator surfaces.
An insulating material used in bulk to wrap electrical cables or other equipment is called insulation. The term insulator is also used more specifically to refer to insulating supports used to attach electric power distribution or transmission lines to utility poles and transmission towers. They support the weight of the suspended wires without allowing the current to flow through the tower to ground.
