Product structure：It is mainly composed of conducting pole, RIP capacitor core, high temperature liquid silicone rubber composite external insulation, equalizing ball, test tap, fittings, etc.
Advantages of bushings：
Ø Unique resin system and special buffer strips
Ø The most advanced production equipment of the world guarantee the better electrical properties, heat-resistance and mechanical properties of RIP bushings series.
Ø The lower weight and smaller volume make it easy for transportation, erection and maintenance.
Ø Oil-free and gas-free design is more environmentally friendly, no risk of explosion；
Ø Excellent performance ensures long-term stable online operation.
