Product Advantages

Proven Insulation Technology: Choose between reliable RIF or RIP solid insulation systems.

Conductor Flexibility: Supports both draw-lead and solid-stem conductor types for design adaptability.

Eliminates Leakage Risk: The monolithic solid core structure prevents any internal leakage between oil chambers, a common failure point in conventional designs.

Custom Design: Configurable for specialized applications.

Suitable Service Conditions for Bushings
Mbient 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.

Ordering Information
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.

3. Installation Details:

Please indicate if a measurement terminal is required. If yes, please provide the required installation dimensions for the terminal.

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.
