The Load-bearing Characteristics Of Epoxy Resin Insulators In Electrical Equipment

The cohesive strength of high voltage epoxy resin stems from its dense molecular structure; the three-dimensional network formed after curing endows the material with excellent compressive and tensile strength. In GIS equipment, basin-type insulators need to withstand mechanical stresses exceeding 15 MPa and high electric fields simultaneously, with a bending strength exceeding 120 MPa, fully meeting the structural requirements for supporting conductors and isolating air chambers. This material's mechanical strength surpasses that of traditional phenolic resins, maintaining stable dimensional accuracy during long-term operation.

In terms of application, high voltage standoff performs exceptionally well in column-type structures. Products cast using the APG process exhibit a smooth and dense surface capable of withstanding vibration and impact. When used with metal inserts, the stress distribution at the bonding interface can be optimized to achieve a uniform state. In equipment with voltage levels from 10kV to 220kV, these insulators serve as both insulation barriers and mechanical supports, fixing electrical components in designated positions.
