Problems solved by technology

However, nuclear power plants have a high risk of fire. After a fire, not only will there be a power outage, but it may also cause environmental pollution and casualties due to the leakage of radioactive materials. In particular, the impact of radioactive materials on the environment is long. Therefore, the safety of nuclear power plants The problem is particularly important
The nuclear island is the collective name of the nuclear reactor and the various systems related to the reactor in the containment of the nuclear power plant. shielding performance, but currently there are a wide variety of cables on the market with different performances, none of which can meet the requirements of nuclear island cables for flame retardancy

Abstract

The invention discloses a nuclear island fireproof cable. The nuclear island fireproof cable comprises a conductor, a fireproof layer wrapping the conductor, an insulating layer wrapping the fireprooflayer, an isolating layer wrapping the insulating layer and a sheath layer wrapping the isolating layer. The isolation layer is prepared from ceramic silicone rubber. According to the nuclear islandfireproof cable provided by the invention, the isolation layer is prepared from the ceramic silicone rubber with specific components, the flame retardance is good, and the spraying prevention performance is excellent.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a nuclear island fireproof cable. Background technique [0002] Nuclear power is characterized by cleanliness, safety, and low fuel consumption, which is very in line with the needs of power development. Nuclear power generation is an inevitable development trend of electric energy. However, nuclear power plants have a high risk of fire. After a fire, not only will there be a power outage, but it may also cause environmental pollution and casualties due to the leakage of radioactive materials. In particular, the impact of radioactive materials on the environment is long. Therefore, the safety of nuclear power plants problem is particularly important. The nuclear island is the collective name of the nuclear reactor and the various systems related to the reactor in the containment of the nuclear power plant. However, there are a wide variety of cables on the market with different...
