Oil Impregnated Paper Transformer Bushings type COT with Composite Insulator More than 20 years Experience Օ Outstanding performance for heavy polluted application Excellent Resistance to vandalism Օ Maintenance free Particularly suitable in seismic area Օ Lower Weight versus porcelain insulator

Composite Insulator Composite insulators are available for our range of products COT from 24 to 550kV as well as for High Current bushings CFPT (Please refer to our catalogues references E322.81, E322.90) Both types of bushings have the same dimensions either if they are with a porcelain or composite insulator. They will be fully interchangeable with existing units. Basic Structure of Hollow Composite Insulators Trench in co-operation with its suppliers has developed a special high quality silicone for its bushing composite insulators. Benefits from Composite Insulators Safety Flashover resistant...

TRENCH' Easy to use Composite insulators have a significant lower weight Easier handling and installation Damaged sheds can be repaired on-site Hydrophobicity The surface of the high voltage composite insulator is hydrophobic, the leakage currents as well as the surface discharge activities are significantly reduced. Lifetime Trench was one of the irst manufacturers to use composite materials for high voltage insulators. Now, composite insulator is a well-established product in the high voltage industry world-wide. Trench has years of experience with electrical and mechanical design, material...
