Epoxy resin insulator is one of polymer insulators usually used on three-phase AC voltage switchgear or other electrical equipment with stable thermal performance.
Epoxy is used in polymer insulators, the product have some advantages
◆ Good appearance,
◆ Excellent machinery performance
◆ Electrical good performance
Selection of the high toughness of epoxy resin production, excellent mechanical properties. And use of low reactivity prescription system, Material curing slowly, low-stress products, products to maximize the mechanical properties.
Using the epoxy in insulators, we may add some other materials to improve epoxy resin insulators performance
◆ Add Activity micro silica, to further improve the mechanical properties of epoxy resin. Ensure more insulation in a damp environment long-term work to maintain good electrical insulating properties.
◆ Add Organic pigments, bright color products, which did not reduce the performance of the insulation products.
The features of epoxy resin insulators
◆ High mechanical strength,
◆ Strong Arc resistance
◆ High compactness
◆ Smooth surface
◆ Good cold resistance
◆ Good heat resistance
◆ Good electrical insulation properties, etc.
Except epoxy resin insulators, polymer insulators are made from silicone rubber popularly used in the worldwide electrical systems.
