Description

Products Description

This LV Bushing for Transformer is a critical component designed for the low-voltage side of oil-immersed distribution transformers. It provides reliable electrical insulation, oil sealing, and stable current transmission between the transformer's internal windings and external circuits.

Key Features

Material & Structure: LV Bushing for Transformer made of high-strength brown-glazed porcelain, with a compact, robust design. It is equipped with a metal flange or base for secure mounting, and its internal cavity accommodates a pure copper conductor for efficient current flow.

Performance: It offers excellent dielectric strength, oil resistance, and anti-aging properties, ensuring long-term stable operation in transformer oil. The design minimizes temperature rise and power loss under rated load conditions.

Standards: Compliant with IEC 60137, DIN 42530, and GB/T 4109 standards, ensuring compatibility and safety in global power systems.

Applications

Primarily used for low-voltage outgoing connections in oil-immersed distribution transformers (1kV and below).

Suitable for various transformer capacities, from small residential transformers to large industrial distribution units.

Available in a range of sizes to accommodate different current ratings (250A, 400A, 630A, 1000A, 2000A, etc.).

We offer various types of insulators:

Type	Description	Application
Pin type	The upper end connects to the conductor, and the lower end is fixed on the cross - arm.	Suitable for distribution lines of 10kV and below.
Suspension type	Can be used in series to enhance withstand voltage capability.	Commonly used in 35kV - 1000kV high - voltage lines.
Post type	Usually installed vertically on the support.	Used in substations and railway electrification.
Bushing	Used for the outgoing lines of conductors in transformers or switchgear.	Insulation for internal outgoing lines of medium and high - voltage equipment.
Line post	Similar to the pin type, suitable for urban overhead lines.	Common in medium - voltage power transmission and substations.
