GLASS DISC INSULATOR

Toughened glass insulators provide the highest level of performance and long-term security for high voltage insulation. 
STRUCTURE
the product consists of cast-iron cap, toughened glass body and pin which are agglutinated together by cement into an integrated piece. Cylindrical head has been adopted for insulators, which is the most advanced structure in the world with superiorities such as less dimension, lighter wieght, higher strength and longer creepage distance which can save metallic materials and reduce transmission line cost. 
most High-voltage lines use ball & socket type toughened glass insulator, which is also called cap & pin. 
ADVANTAGES

• Zero spontaneous breakage and easy inspection.
• Excellent arc-resistance and vibration-proof performance.
• Good self cleaning and leass ageing.
• Large electric capacitance, homogenous distribution of voltage on single string insulators

MECHANICAL & VOLTAGE RATING
40kN up to 300kN, 11kV up to 765kV.
STANDARD
Tronco Electric glass insulators compply with IEC60383.
APPLICATION
the glass insulators are applied in HV and Extra HV transmission lines as dielectric and use for supending conductors.
