Our Wall Bushings are engineered for safe and stable power passage through walls or floors in substations, featuring a revolutionary solid insulation design.

End of Leakage Problems: Unlike traditional oil-impregnated paper bushings (prone to oil leakage, aging, poor seismic performance) or so-called "dry-type" bushings with silicone oil filler, our bushings have nothing to leak.

Monolithic Solid Structure: Whether RIF or RIP, the core is a single, void-free solid dielectric with no internal seals to fail and no fillers to degrade.

Ultimate Reliability: This seamless construction guarantees exceptional dielectric performance, mechanical strength, and seismic resistance over the entire service life.

Custom Design: Available for a wide range of wall thicknesses and mounting configurations.

Altitude: Applicable for installations at or below 2000m above sea level.

Ambient Temperature: Suitable for -50 °C to +50 °C.

Installation Angle: Can be installed at any angle.

Pollution Class: Suitable for heavily polluted areas, Class III or higher.

When placing an order, please specify:

1. Electrical Parameters: Rated voltage, rated current, rated frequency, external insulation creepage distance, internal insulation clearance, oil-end length, draw-lead length, CT mounting position length.

2. Environmental Parameters: Ambient temperature, altitude, pollution class.

3. Installation Details: If a through-type CT is to be fitted, specify whether split-type or integrated-type CT is required, with relevant CT parameters.

4. Model Designation: The letter "F" indicates silicone rubber composite sheds. Absence of "F" indicates porcelain sheds.

Note: Custom flange and terminal dimensions available. Direct replacement bushings also supplied.
