GFRP Dry Wall Bushing

Description:

Oil-free, gas-free, no filling, maintenance free;

Large insulation margin for the design, semiconductor capacitance screen, with raise discharge inception voltage to the maximum extent, with no partial discharge in operation;

Heat resisting and dire-retardant insulating material, with no decomposition stable electric property, and no danger of combustion or explosion;

Compact structure, small volume, lightweight, convenient transportation, installation at any angle;

Reinforced winding of fiberglass and optimized mechanical lay own design with high bend strength, excellent mechanical property, suitable for earthquake affected areas;

Short processing cycle, customized according to customer requirements;

Slastic composite shell has good antifouling property, self-cleaning without sweeping and applicable in heavily polluted areas;

Long service life, low long-term running cost.
