Performances
Excellent Insulation: High insulation materials (BMC/DMC, epoxy) provide high breakdown voltage and reliable withstand capability.
Flexible Structure: Available in shed, block, or wedge designs to optimize creepage distance and mechanical support.
High Strength & Durable: Dense, uniform molded/cast construction offers excellent impact resistance without the fragility of porcelain.
Flame Retardant & Weather Resistant: V0-rated, operates at ≥150°C, and resists moisture and dust.
Convenient & Economical: Bolt fixing with embedded inserts for easy installation; low maintenance—just cleaning and crack inspection.
Technical Specifications
Customized insulation parts (wedge-shaped, stepped, with locating holes, etc.) can be supplied based on transformer coil dimensions, clamp mounting hole patterns, and compression force requirements, achieving dimensional accuracy within ±0.5mm.
Applications
Dry-type Transformer HV Side: Insulation support between live conductors and the grounded enclosure.
Between Windings and Core/Clamps: Insulation isolation and support/compression between HV/LV windings and metal parts.
Winding Ends: Positioning insulation to prevent turn-to-turn shorts caused by coil movement.
Indoor Switchgear: Insulation support for busbars and live parts in switchgear and ring main units.
