10/20/35/110kV Oil-Immersed Transformer

10/20/35/110kV Low-Loss, High-Safety Oil-Immersed Core Power Distribution Transformer.

Low loss

Low noise

Strong Short-Circuit Resistance

Attractive Appearance

Product Description

The core of the 110kV oil-immersed power transformer is made of high-quality grain-oriented silicon steel sheets stacked in multi-step steps, with a cured coating on the surface. It features low loss and low noise. The coil adopts an inner and outer support strip structure, and high-strength hard paper tube structure is used between the coil and the core, as well as between coils, effectively ensuring resistance to sudden short-circuit impact. The body and tank are positioned with an all-around positioning structure to ensure stability during transportation and operation, with an elegant and generous appearance.

Low loss

Complies with the energy efficiency requirements of the "Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Power Transformers" standard.

Low noise

Meets the low-noise standard requirements of State Grid / China Southern Power Grid.

Strong Short-Circuit Resistance

The coil interior is supported by a high-quality insulating framework, and the tank side wall is laser-cut in one pass.

Attractive Appearance

Full polishing and rust removal, powder electrostatic spraying achieves appliance-grade finish.
