Product descriptions from the supplier
Description
Product Introduction
Our 6-35kV (including 33kV) oil-immersed neutral grounding resistance transformers, also known as earthing transformers, are designed for medium-voltage grids. Using oil cooling technology, they safely dissipate heat. By creating a neutral point connection with a grounding resistance, these transformers quickly detect and limit ground faults. Ideal for enhancing grid reliability, they offer robust protection against electrical failures, ensuring stable power supply for industrial and commercial applications.

Performance Advantages
Energy-Efficient & Eco-Friendly: Low-loss, low-noise, and high-efficiency design reduces energy consumption and environmental impact.
Fully Sealed & Maintenance-Free: No oil storage tank required. Corrugated tank design automatically adjusts for oil volume changes, eliminating leakage risks.
Extended Lifespan: Sealed structure isolates oil from air, slowing degradation and insulation aging. Reduces maintenance costs and extends operational life.

Transmission LineIn transmission lines, a "π" connection involves breaking the original line from Substation A to Substation B and inserting Substation C, forming a "π" configuration. After the "π" connection, the original single line is divided into two independent transmission lines. Following the "π" connection, Substations B and C may both be powered by Substation A (in this case, Substation C receives power via a feeder from Substation B's busbar, or possibly from another voltage point within Substation B);Encyclopedia09/04/2025 -
