The cast of motor insulating envelope.Such as electromagnet, contactor coil, transformer, the entirety of dry-type transformer high and low voltage electrical equipment
The manufacture of hermetically sealed insulating envelope.It is developed rapidly in electrical equipment industry.Had developed to from normal pressure casting, vacuum pouring
Automatic pressure gel is molded.
Epoxy resin is a kind of to have high dielectric property, resistance to surface leakage, resistance to due to epoxy-resin systems after its solidification
The superior isolation material of electric arc；Epoxy-resin systems after solidification have excellent mechanical property；Epoxy resin body after solidification
System has excellent alkali resistance, acid resistance and solvent resistance.Epoxy resin is highly suitable for the cladding master in high-tension switch gear
APPENDIX MATERIALSThe in the insulating materials and high-tension switch gear in loop as insulating materials.Major loop in existing high-tension switch gear
Electric-conductor mostly using airbreak laying installation, do not carry out cladding sealing protection to electric-conductor, short circuit easily produced between circuit
Or the external world is discharged, while electric-conductor also exacerbates the extent of corrosion of electric-conductor with air contact for a long time, shortens height and presses off
Close the service life of equipment.

Preferred scheme, closure blind hole are internally threaded hole, and the screwed hole is insert nut 4.
Preferred scheme, mounting hole 2 are regular hexagon hole.
Preferred scheme, closure seamed edge are provided with fillet, and the radius of corner is not less than 0.5 millimeter.
The present invention compared with prior art, has the following advantages and advantages：After epoxy resin is due to its solidification
Epoxy-resin systems are a kind of with high dielectric property, resistance to surface leakage, the superior isolation material of resistance to electric arc；Epoxy after solidification
Resin system has excellent mechanical property；Epoxy-resin systems after solidification have excellent alkali resistance, acid resistance and resistance to molten
Agent.Protection electric-conductor and other conductors can be played by carrying out electric-conductor on blocking high-pressure switchgear major loop using the closure
Between security, prevent that phase fault or externally electric discharge occur between major loop, reduce it is alternate between external conductor away from
From reducing the manufactured size of high-tension switch gear, while electric-conductor is sealed using closure, prevented to connect with outside air
Touch, prevent electric-conductor from producing oxidation for a long time.
