    product description

    DIN 1KV630 Transformer Bushing Insulator is an electrical component that meets the DIN Standard(Germany Standard)
    Rated Voltage: 1 kV
    Rated Current: 630A
    Creepage Distance: Min 75 mm

    Key Features:
    Material: Typically made of porcelain or composite polymer for high dielectric strength and weather resistance.
    Design: Flanged or threaded mounting for secure attachment to transformer tanks.
    May include oil barriers (for oil-filled transformers) or gas sealing (for SF₆transformers).
    Standards Compliance: Manufactured according to DIN 42523, DIN 47636, or other relevant standards for high-voltage bushings.

    Usage:
    Primary Application: Used in power transformers, distribution transformers, and switchgear to safely insulate and route high-voltage conductors entering/exiting the transformer tank.

    Functions

    1.Provides electrical insulation between the live conductor and the grounded transformer tank.
    2.Ensures mechanical stability for conductor connections.
    3.Prevents oil/gas leakage in sealed transformers.

    Common Variants:
    Oil-impregnated paper-insulated bushings (for oil-filled transformers).
    Resin-impregnated or dry-type bushings (for dry-type transformers).
    SF₆gas-insulated bushings (for gas-insulated switchgear).
