Dry-type Wall Bushing,
RIF/RIS Wall Bushing
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, and poor seismic performance) or so-called "dry-type" bushings with silicone oil filler (suffering from partial discharge and poor mechanical strength), our bushings have nothing to leak.
Monolithic Solid Structure: Whether RIF or RIP, the core is a single, void-free solid dielectric. There are 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.
For altitudes exceeding 2000m, the technical specifications shall be subject to agreement between the supplier and the purchaser.
Ambient Temperature: Suitable for a range of -50 °C to +50 °C.
For environments outside this range, the technical specifications shall be subject to agreement between the supplier and the purchaser.
Installation Angle: Can be installed at any angle.
Pollution Class: Suitable for use in heavily polluted areas with a classification of Class III or higher.
When placing an order, please specify the following parameters:
1. Electrical Parameters:
Rated voltage, rated current, rated frequency, external insulation creepage distance, internal insulation clearance, oil-end length, draw-lead length (critical), CT mounting position length (critical).
2. Environmental Parameters:
Ambient temperature, altitude, pollution class.
3. Installation Details:
If a through-type current transformer (CT) is to be fitted, please specify whether a split-type or integrated-type CT is required, and provide the relevant CT parameters.
4. Model Designation:
The letter "F" in the model number (e.g., for Transformer Bushing, GIS Bushing, or Wall Bushing) indicates the silicone rubber composite sheds. The absence of "F" indicates the porcelain sheds.
Note: The dimensions of the bushing flange and terminals can be custom-designed according to the transformer manufacturer's requirements. We also supply direct replacement bushings for existing installations.
