Product descriptions from the supplier
Overview
DDHV V type center break disconnector is a compact, reliable and easy-to operate substation equipment.
Suitable for applications up to 145 kV voltage level, DDHV is designed for installation in outdoor switchyards. It has two moving insulators per phase arranged in a ‘V’ configuration, which makes DDHV design compact and simple. Due to this, DDHV is a preferred solution for substations where space is costly or limited.
DDHV disconnectors enable flexible design and reliable operations. Built-on earth switches are available and can be mounted on one or both sides of the disconnector.
Applications
Substations in small areas
Pole-top mounted
Mobile substations

How Does Oil Loss Affect SF6 Relay Performance?1.SF6 Electrical Equipment and the Common Problem of Oil Leakage in SF6 Density RelaysSF6 electrical equipment is now widely used in power utilities and industrial enterprises, significantly advancing the development of the power industry. The arc-quenching and insulating medium in such equipment is sulfur hexafluoride (SF6) gas, which must not leak. Any leakage compromises the reliable and safe operation of the equipment, making it essential to monitor the SF6 gas density. Currently, mechanicalFelix Spark10/21/2025 -

Grounding Causes of Cable Lines and the Principles of Incident HandlingOur 220 kV substation is located far from the urban center in a remote area, surrounded primarily by industrial zones such as Lanshan, Hebin, and Tasha Industrial Parks. Major high-load consumers in these zones—including silicon carbide, ferroalloy, and calcium carbide plants—account for approximately 83.87% of our bureau’s total load. The substation operates at voltage levels of 220 kV, 110 kV, and 35 kV.The 35 kV low-voltage side mainly supplies feeders to ferroalloy and silicon carbide plantsFelix Spark10/21/2025 -
