A nuclear power trailing cable

Abstract

The invention discloses a nuclear power towing cable, which relates to the field of cable technology. The nuclear power towing cable includes an outer sheath, a shock absorber, a main wire, a ground wire, and a filling strip; TPU, the outer sheath is tightly covered on the outside of the shock-absorbing sleeve; the shock-absorbing sleeve is a reinforced natural rubber material; the main line includes a main line conductor and a main line insulating sleeve tightly covering the outside of the main line conductor, The ground wire includes a ground wire conductor and a ground wire insulation sleeve tightly wrapped on the outside of the ground wire conductor; the filling strip is a rope-shaped body made of low-cost lightweight insulating material, and the present invention is arranged inside the cable The filling can achieve multiple cushioning, further buffering force, reducing friction damage between each other, improving the structural reliability of the cable, prolonging the service life, and having higher safety.

Description

Technical field [0001] The present invention relates to the field of cable technology, in particular to a nuclear power towed cable. Background [0002] Global energy is very scarce, in order to respond to energy conservation, environmental protection, emission reduction, the world is vigorously accelerating the development of nuclear power energy, of which nuclear power is the main direction of the future power structure adjustment, an installed capacity of 1 million kilowatts of nuclear power plants and the same scale of thermal power plants compared with the annual coal consumption of 3 million tons, reduce carbon dioxide emissions by 7.41 million tons, so the development of nuclear power for energy conservation, environmental protection, emission reduction is of great significance. [0003] Wire and cable are used to transmit electrical (magnetic) energy, information and wire products that realize electromagnetic energy conversion. Broad wire and cable is also referred to as ...

AI Technical Summary

Problems solved by technology

In the broad sense, wires and cables are also referred to as cables for short. In the narrow sense, cables refer to insulated cables, which can be defined as: a collection of the following parts; one or more insulated cores, and their respective possible coatings. Protective layer and outer sheath, cables can also have additional uninsulated conductors. As the main carrier of power transmission, wires and cables are widely used in electrical equipment, lighting lines, household appliances, etc., and their quality directly affects engineering. Quality and personal and property safety. Among them, the use of cables in nuclear power plants is also very common. The environment of nuclear power plants is special, so the performance requirements for cables are particularly strict. Towing cables often face frequent dragging, twisting and scratching. At the same time, they are also vulnerable to vehicles. Direct rolling, if the wear resistance, pressure resistance, and toughness are insufficient, it is easy to have problems such as damage, distortion, and even leakage, resulting in safety accidents

[0004] At present, there are few reports on the trailing cables used in nuclear power plants
