NJREC transformer bushings and insulators for industry use

OIP Capacitive Bushing

OIP transformer bushings use oil-impregnated paper condenser cores to provide electrical insulation for oil-to-air, oil-to-oil and oil-to-SF6 connections.

RIP Capacitive Bushing

NJREC RIP bushings use a resin impregnated paper condenser core to insulate high-voltage connections

High Current Bushing

NJREC high-current transformer bushings rated 24 kV and 40.5 kV, with 5000–35000 A options.

Oil to Oil Bushing

NJREC oil-to-oil transformer bushings connect oil-filled compartments with RIP or RIS cores. IEC 72.5–550 kV, IEEE 69–500 kV, up to 2500 A.

Oil to SF6 (gas) Bushing

Oil-to-SF6 bushings connect oil-filled power transformers to gas-insulated switchgear, using RIP or RIS condenser cores for electrical insulation.

RIS Capacitive Bushing

RIS transformer bushings use resin-impregnated synthetic insulation to carry current safely through the transformer tank.

High Voltage Porcelain Bushing

Porcelain high voltage bushing rated 1‑52 kV and 250‑6300 A, compliant with DIN/EN/IEC, variety of creepage & termination options, suitable as power transformer bushing or transformer bushing insulator.

Standard Type Glass Insulator

NJREC standard toughened glass insulators insulate and support overhead power line conductors.

Fog Type Glass Insulator

Fog type toughened glass insulators provide electrical insulation and mechanical support for overhead lines in coastal and polluted environments.

Double Shed Glass Insulator

Double shed glass insulators provide electrical insulation and mechanical support for overhead power lines in polluted environments.

RTV Coated Glass Insulator

RTV-coated glass insulators combine toughened glass with a hydrophobic silicone coating to support conductors and reduce pollution flashover risk.

Wall Bushings

NJREC wall bushings provide insulated, air-to-air conductor passage through grounded walls for substation and switchgear installations.

EN Porcelain Transformer Bushings

NJREC porcelain transformer bushings follow EN 50386, EN 50180 and EN 50243 standards to provide insulated electrical connections through transformer tanks.

DIN Porcelain Transformer Bushing

NJREC offers DIN porcelain transformer bushings for transformer terminal connections across different DIN standards, rated from 1 to 52 kV and 250 to 8000 A.

ANSI Transformer Bushings

ANSI porcelain transformer bushings connect transformer windings to external circuits while insulating conductors from the grounded tank.

ANSI Spade Type Porcelain Bushings

ANSI spade type porcelain bushings provide electrical insulation and bolted conductor connections through transformer tanks.
