Compound pad

BMC(Bulk Molding Compound) dry type transformer rubber pad is used for electrical insulation and weight bearing to guarantee steady transportation and operation of dry-type transformer and its insulation properties. It can also promote the electrical properties of dry-type transformer and guarantee long service life in high salt density and heavily polluted areas. SHIRE has successfully developed a new type compound insulation pad for dry-type transformers.

Features

Product advantages

SHIRE compound pad adopts BMC as main body coated with HTV(high temperature vulcanized) silicon rubber. It has following properties:

1、Excellent Mechanical Properties

SHIRE compound pad mainly adopts BMC compound material to produce. BMC is made of high activity unsaturated polyester resin or its modified resin as matrix, and also mixed with low shrink resin, chopped glass fiber, inorganic filler, modifier, mold discharging agent and pigment. It has good mechanical properties.

2、Excellent Insulation Properties

SHIRE rubber pad coated layer HTV silicon rubber is widely used in power system. It has good insulation properties by its skirt design structure to add the creeping distance.

3、Advanced Production Technology

BMC compound pad adopts one time injection forming technology under high temperature and pressure with uniform and better quality.
