Abstract
A temperature-resistant radiation-tolerant anti-cracking IE-class control cable for a nuclear power plant relates to the field of a production technology of a cable for a nuclear power plant. A cable taped covering is arranged outside four insulated conductors; a shielding layer, an oxygen barrier, a high stopband taped covering and a 135-DEG C halogen-free flame retardant cross-linked polyolefin outer sheath are successively arranged outside the cable taped covering. Alkali-free glass fiber wires are arranged among the insulated conductors in the cable taped covering. Each insulated conductor is composed of an oxygen-free copper wire, a crosslinked polyethylene inner insulating layer disposed outside the oxygen-free copper wire and a crosslinked polyether-ether-ketone outer insulating layer arranged outside the inner insulating layer. The cable provided by the invention has a simple structure. By the adoption of a double insulated composite structure and a novel insulating material with a special medium added therein, organic unity of electrical property, flame resistance and long-life performance is realized greatly.
Description
Technical field
The present invention relates to a kind of cable for nuclear power station production technical field, be specifically related to a kind of heatproof radiation hardness cracking resistance used in nuclear power station IE level control cables.
Background technology
Heatproof radiation hardness cracking resistance used in nuclear power station IE level control cables, not only will have the general characteristic of common cable, and should have long, low cigarette of life-span, Halogen, fire-retardant performance, also will have specifically environment resistant (as radiation hardness, anti-LOCA).The nuclear safety that Japan's violent earthquake causes has caused people's self-examination, and heatproof radiation hardness cracking resistance used in nuclear power station IE level control cables has higher fail safe and more excellent economy.
Summary of the invention
Purpose of the present invention is exactly in order to overcome the deficiency of common nuclear cables technology, and a kind of heatproof radiation hardness cracking resistance used in nuclear power station IE level control cables that meets the cable standard requirement of generation Ⅲ nuclear power station is provided.
The present invention includes four eradication edge wires, outside four eradication edge wires, be arranged to the cable lapping layer, set gradually screen, oxygen barrier layer, high stopband lapping layer and 135 ℃ of non-halogen flame-proof cross-linking polyolefin outer jackets outside the stranding lapping layer; Between described insulated conductor in described stranding lapping layer, the alkali-free glass wool rope is set; Described every eradication edge wire is by copper free wire and be arranged on the outer crosslinked polyethylene inner insulating layer of copper free wire, be arranged on the outer crosslinked polyethers ether ketone external insulation layer of described inner insulating layer forms.
The present invention is copper free wire at the conductor of every eradication edge wire, and adopted the double hyer insulation design: crosslinked polyethylene inner insulating layer and crosslinked polyethers ether ketone external insulation layer, the crosslinked polyethylene inner insulating layer has high electrical property and mechanical and physical performance, and crosslinked polyethers ether ketone external insulation layer has the anti-flammability of assurance insulated wire cores and the function of radiation resistance.The present invention also adopts the inserts that the alkali-free glass wool rope is stranding, can guarantee high flame retardant and the rounding property of product.After the wrapped stranding of high flame retardant twining package tape, set gradually from inside to outside screen, oxygen barrier layer, Halogen band lapping layer, 135 ℃ of non-halogen flame-proof cross-linking polyolefin outer jackets.The wrapped stranding of high flame retardant twining package tape plays to be tightened and fire resistance.
The present invention is simple in structure, adopts double hyer insulation composite construction and the new insulation material that adds special media, has realized preferably the organic unity of electrical property, fire resistance and long-life performance.
The accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
The present invention is provided with four eradication edge wires, and every eradication edge wire is by copper free wire 1 and be arranged on the outer crosslinked polyethylene inner insulating layer 2 of copper free wire 1, be arranged on inner insulating layer 2 outer crosslinked polyethers ether ketone external insulation layers 3 forms.
Set high the fire-retardant cable lapping layer 5 that is coiled at four eradication edge wire peripheral hardwares, set gradually screen 6, oxygen barrier layer 7, high stopband lapping layer 8 and 135 ℃ of non-halogen flame-proof cross-linking polyolefin outer jackets 9 outside high flame retardant is coiled into cable lapping layer 5.Between four eradication edge wires in high flame retardant is coiled into cable lapping layer 5, alkali-free glass wool rope 4 is set.
