Product Advantages

Flexible Conductor Design: Offered in either draw-lead (cable) or solid-stem conductor configurations to suit various connection needs.

Solid & Sealed: The solid dielectric core eliminates common oil leakage and moisture ingress issues, guaranteeing stable performance.

Custom Design: Tailored to your specific electrical and mechanical interface requirements.

Designed for the external connection point of oil-immersed transformers, providing a reliable interface between the transformer's internal oil environment and the external air-side connection.

Suitable Service Conditions for Bushings

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.

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

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.
