Pipeline Antifreeze Electric Heat Tracing For Nuclear Power Plant

Pipeline Distribution Trace Mineral Insulated Cable for Nuclear Power Plant is designed specially for electric heat tracing for the use of antifreeze and thermal insulation for the instruments, material pipelines, measurement pipelines, analysis and sampling pipelines, etc. The solution is used to prevent freezing, crystallization, precipitation, condensation and other phenomena in low temperature environment for a nuclear power plant operation especially during the winter season. There are three types of cable can be selected to be used in this applications including constant wattage, self-regulating and mineral insulated cables.

A nuclear power plant is an industrial site intended for the production of electricity, which uses as boiler one or more nuclear reactors supplied with nuclear fuel (source of energy). The power of a power station varies from a few megawatts to several thousand megawatts depending on the number and type of reactor in service on the site (900 MWe or 1300 MWe in France per reactor). Electricity is produced by a chain reaction (nuclear fission) producing heat that will then generate steam. The steam thus produced makes it possible to rotate generators that flow on the national electricity grid.

To avoid the crystallization of the process fluids or the water freezing, heat Tracing is often installed on critical circuits and is therefore an essential equipment for safety.
