Product descriptions from the supplier
Description：
UniGear 500R is very space efficient solution, designed to reduce the width of the medium-voltage airinsulated switchgear. Panel design is only 500 mm wide for feeder current up to 2000 A.Its compact design makes UniGear 500R ideal for container installation for primary distribution.
One of the main characteristics of the UniGear 500R switchgear is the isolation of the circuit-breaker from the main busbars by means of the three position disconnector.

Q: What’s the difference in the circuit breaker for air-insulated vs gas-insulated?
A:
Air-insulated switchgear circuit breaker is typically removable or withdrawable. The circuit breaker is based on vacuum circuit technology. In the gas-insulated, it is fixed mounted. The function of withdraw is provided by a separate disconnecting switch. Typically, a three-position switch with connected, disconnected, and ready-to-earth position.
Q: What are the key features of ABB’s medium voltage switchgear products?
A:
ABB‘s primary medium voltage switchgear products are designed to connect and protect the evolving grid. They feature robust construction, advanced safety mechanisms, high reliability, and ease of maintenance. They are designed to handle high electrical loads and provide efficient power distribution with minimal losses.

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 -
