High voltage switch insulation cover

The GIS high-voltage switch tank heater is composed of three parts, silicon rubber heating sheet, 20mm thick EPDM foam board insulation layer, stainless steel plate or aluminum plate shell. The heater is divided into two-piece combined structure, which is convenient and quick to install and disassemble. During the heater operation, the other one is in standby state while the other one is working, and the two heat tracing plates do not work at the same time. The GIS high-voltage switch tank heate

Gas-insulated high-voltage switchgear (GIS) is a compact metal encapsulated switchgear consisting of high-voltage components such as circuit-breakers and disconnectors, which can be safely operated in confined spaces. GIS is used where space is limited, for example, extensions, in city buildings, on roofs, on offshore platforms, industrial plants and hydropower plants. Hitachi Energy has always been and continues to drive innovation in GIS technology in ratings, operations, switching technology, smart control and supervision, and compactness. 



High safety and good insulation performance. The heating plate is composed of nickel-chromium alloy etched heating plate or nickel-chromium alloy heating wire and silicon rubber high-temperature insulating cloth. Waterproof, long life and so on.

High reliability, good anti-vibration and anti-shock performance. The heating surface of the heating plate adopts the high-performance "468MP" double-sided tape produced by 3M Company in the United States, which has the characteristics of strong adhesion, good shock resistance and waterproof.

High adaptability, with weather resistance, high temperature resistance, low temperature resistance, aging resistance, ozone resistance and chemical resistance; it is completely moisture-proof, waterproof and oil-proof to ensure that it can still work normally under long-term moisture.

The GIS high-voltage switch tank heater attaches the protective layer, the thermal insulation layer and the heating layer to the top, and does not need to be covered on the tank body, which saves the installation time, and the heater adopts silica gel with good insulation performance. heating plate. The insulation layer adopts EBDM closed-cell foaming. The waterproof junction box is arranged on the outer wall of the protective shell and is connected with the shell to completely solve various defects of the previous heater.

The heater can be installed with temperature control, thermal probe, overheat protection switch and other temperature control components according to customer requirements.
