Product:
1. The description of insulation silicon rubber for composite
insulator with superior performance high voltage.
The product is designed and produced strictly in accordance with
the DL/T376-2010 standard, and has passed the testing and
certification of Wuhan Electrical Equipment Institute of China
Electric Power Research Institute and Xi'an High Voltage Electrical
Appliance Research Institute. It has excellent physical and
mechanical properties, electrical properties, hydrophobicity, aging
resistance, good interface adhesion, and excellent surface
glossiness. This product already contains vulcanizing agent, and
there is no need to add it separately during the processing.
Multiple colors and packaging types can be provided according to
user needs.

The product is suitable for injection and molding, it is a
specialized silicone for producing medium voltage composite
insulators, composite lightning arresters, transformers, fuses and
other transmission equipment.
Heat resistance: Silicone rubber has much better heat resistance
than ordinary rubber, and can be used almost permanently at 150
degrees Celsius without any performance changes; Can be used
continuously for 10000 hours at 200 degrees Celsius; It can also be
used for a period of time at 350 degrees Celsius.
Cold resistance: Ordinary rubber has a delay of -20 degrees to -30
degrees, while silicone rubber still has good elasticity at -60
degrees to -70 degrees. Some special formulas of silicone rubber
can also withstand extremely low temperatures.
Weather resistance: Ordinary rubber rapidly degrades under the
action of ozone generated by corona discharge, while silicone
rubber is not affected by ozone. Moreover, under long-term exposure
to ultraviolet radiation and other climatic conditions, its
physical properties only show slight changes.
