1.Overview

High Voltage MV&HV Drain Valve is a specialized valve designed specifically for high-voltage power transformers (especially in scenarios such as American box-type transformers and pre-assembled substations). Its core function is to safely release the oil and gas pressure generated within the transformer due to insulation failure, localized overheating, or arc discharge. It also takes into account sealing reliability, corrosion resistance, and operational convenience. Its design complies with American power industry standards (such as the IEEE C57 series, ANSI/IEEE 386). It is compatible with the structural characteristics of American transformers (such as compact oil tanks and flange interface specifications). It is a key component for ensuring the safe operation of transformers.

 2.  Features

Precise pressure relief, preventing overpressure explosion

Fully sealed protection, no leakage

Anti-oil erosion and long-life design

It is compatible with American-style transformers.

3.Applications

Mainly applied to American-style high-voltage transformers (such as American-style box-type substations, modular transformers, prefabricated substations), especially suitable for:

· 1). Scenarios with high requirements for equipment safety in urban distribution networks, industrial parks, etc.;

· 2). Corrosive environments such as high humidity, salt spray or chemical parks (requires selection of anti-corrosion coating valve bodies);

· 3). Intelligent substations that require frequent inspection or are unmanned (recommended to have signal feedback function).
