This product is suitable for power systems with rated voltages of 12kV, 24kV, and 40.5kV, rated currents of 400/630A, and frequencies of 50/60Hz. It is a high-performance, long-life switch capable of closing and interrupting load currents and carrying fault currents during transfers, compliant with standards such as IEC 60265 and GB 3804. The product features a stainless steel housing, extremely short arc duration (within half a cycle), and contacts made from arc-quenching materials, ensuring a long service life and enhanced capability to interrupt short-circuit currents. It can be operated manually or by a DC motor located in the motor compartment beneath the housing.
This product is suitable for use in ring main power supply systems, dual power supply systems, or terminal power supply systems operating at 7.2kV, 12kV, 24kV, 40.5kV, and 72kV, serving as high-voltage distribution metering, compensation control, and protection devices. In addition to the transformer, the pre-assembled substation is equipped with a four-position load switch, a two-position load switch, backup protection fuses, and plug-in fuses on the high-voltage side. The low-voltage side is assembled with control devices, distribution devices, compensation devices, and energy meters according to customer requirements.
Tin-plated cast red copper.
Massive productions of surge arrester (MOA),either with porcelain or polymeric housing, are suitable in the systems of power generation,power transmission,power transformation, and power distribution under AC 220kV and below.
