Description

{Radiationproof and Noncombustible Temperature wire}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radioactive fire retardant heat-resistant cable suitable for a special purpose which can be used in a fire prevention environment including at least one conductor, an insulation layer surrounding the conductor, and a fireproof insulation layer surrounding the insulation layer. Ovens, heaters, furnaces, kilns, and cables used in construction.

As is well known, the radioactive incombustible heat-resisting cable is insulated with polyether ether ketone (PEEK), which has the highest radiation resistance among the polymeric insulators, and is insulated with glass fiber and ceramic fiber to be used in a radioactive incombustible environment Cable.

These radiation-resistant fire-proof heat-resistant cables should be designed in accordance with building environmental conditions such as radiation and fire prevention. Polymer insulation flame retardant cables used in conventional fire-retardant cables are satisfactory in preventing the spread of fire, And it is impossible to prevent burning due to fire. Therefore, it has been proposed to develop a special cable that can be used in nonflammable (about 1400 ° C) by reinforcing with ceramic fiber due to the function limit of electric wire. In addition, it has been proposed to develop a special cable which is insulated with polyether ether ketone (PEEK), which is an engineering plastic polymer with excellent radiation characteristics, and has improved heat and radiation properties.

Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an operation and a durability which are used in a radioactive incombustible environment.

In order to achieve the above object, the present invention provides a method for manufacturing a copper-clad laminate, comprising the steps of: inserting a nickel-plated copper wire or a pure nickel conductor with polyetheretherketone (PEEK) It is wrapped with a nickel wire, and the outermost layer is structured by braiding with ceramic fiber.

In accordance with the present invention, it is possible to design a radiation-resistant fire-resistant heat-resistant cable satisfying the fire-resistant characteristic and flexibility of the cable in accordance with the extreme environment of radiation-resistant fire-proof property and meeting the requirements of the electric wire and the underground building or the electric wire market for the subway in the future It is possible to satisfy various requirements of customers.

2 is a cross-sectional view of a radiation-resistant fire-proof heat-resistant cable according to another embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view of a nickel-plated copper wire or pure nickel wire 10 which is insulated with polyetheretherketone 20 and shielded with double glass fiber 30, 40 which surrounds the insulation layer, And they are wrapped with a ceramic fiber 60 in a woven form.

2 is a cross-sectional view of a nickel-plated copper wire or pure nickel wire 10 which is insulated with a polyetheretherketone 20 and shielded by double glass fiber 30, 40 which surrounds the insulating layer, Pure nickel wires 50 and then wrapped with ceramic fibers 60 in a woven form.

The number of times the ceramic fibers 60 are wrapped can be adjusted according to customer requirements.

Here, glass fiber and ceramic fiber are coated with tetrafluoroethylene (TFE) or silicone varnish.

Ceramic fiber is suitable for non-burning environment at melting point of about 1800 ℃, and it is flexible and easy to process, making it a material suitable for customer's specification. These radioactive fire-retardant heat-resistant wires shall be manufactured in accordance with the Hazardous Substances Control Law (RoHS) of the European Union's Electrical and Electronic Equipment Regulations.
