Abstract

The utility model relates to the technical field of a cable structure, in particular to a zero-halogen, low-smoke and flame-retardant crosslinked polyolefin insulated and sheathed nuclear-grade control cable comprising seven stranded cable cores, each cable core comprises a plurality of copper conductors and crosslinked polyolefin insulating layers arranged at the periphery of the copper conductors, polyester tapes are wound at the periphery of the seven cable cores, aluminum-plastic composite tape shielding layers are wound at the periphery of the polyester tapes, a drainage wire which is stranded by multistrand tinned copper wires is arranged between the polyester tape and the aluminum-plastic composite tape shielding layer, a zero-halogen, low-smoke and flame-retardant inner sheath is extruded outside the aluminum-plastic composite tape shielding layer, a tinned copper wire braiding shielding layer is arranged at the periphery of the zero-halogen, low-smoke and flame-retardant inner sheath, and a zero-halogen, low-smoke and flame-retardant polyolefin outer sheath is arranged at the periphery of the tinned copper wire braiding shielding layer. The control cable not only has excellent electrical performance and anti-interference performance, but also has good fire-resistant property. The product performance meets the related requirements of RCC-E, the qualification test procedure falls into the K3 category, and GB50217 requirement is met.

Description

Insulation of LSOH anti-flaming cross-linked polyolefin and sheath nuclear level control cable
Technical field
The utility model relates to a kind of technical field of structures of cable.
Background technology
Quickening along with Chinese society economic construction paces, to reaching the cable that to carry out its predetermined function under the seismic (seismal under the external normal condition of nuclear reactor (pressure water reactor or boiling-water reactor) containment that is used for nuclear power station, high especially to its performance requirement, common nuclear level control cable has not satisfied its requirement, and safety also can not get ensureing.
The utility model content
The purpose of this utility model is in order to satisfy above requirement, a kind of LSOH anti-flaming cross-linked polyolefin insulation and sheath nuclear level control cable to be provided.
The purpose of this utility model is achieved in that insulation of LSOH anti-flaming cross-linked polyolefin and sheath nuclear level control cable, comprise seven mutual stranded cores, every core is made up of the cross-linked polyolefin insulating barrier of some copper conductors and copper conductor periphery, at the wrapped polyester belt of the periphery of seven cores, the wrapped aluminium-plastic tape screen of the periphery of polyester belt, between polyester belt and aluminium-plastic tape screen, be provided with one by the stranded drainage thread of multiply tinned copper wire, the aluminium-plastic tape screen extrudes the LSOH anti-flaming inner sheath outward, the periphery of LSOH anti-flaming inner sheath is provided with the tinned copper wire woven shield, and the periphery of tinned copper wire woven shield is provided with the halogen-free and low-smoke flame-retardant polyolefin oversheath.
The utility model is by above design, and cable insulation is the cross-linked polyolefin material, and the conductor working temperature is 90 ℃, and short circuit working temperature and time are 250 ℃/5s.Adopt the wrapped shielding of aluminium-plastic tape to squeeze the low-smoke non-halogen flame-retardant inner sheath outward, tinned copper wire braid shielded double-layer shielding structure has again guaranteed the anti-external interference ability of cable.Oversheath also adopts LSOH anti-flaming cross-linked polyolefin protective cover material, makes cable have the low smoke, zero halogen characteristic, and rate of propagation is slow when fire takes place, and smoke density is low, and the pernicious gas burst size is little, is convenient to personnel and withdraws, and has also avoided the injury to instrument and equipment.The beneficial effects of the utility model are: the utility model not only has good electric property and interference free performance, and has good fire-resistance property.Properties of product meet the RCC-E related request, and qualification test procedure is " K3 " class, and meet the requirement of GB50217.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure, 1 copper conductor, 2 cross-linked polyolefin insulating barriers, 3 polyester belts, 4 aluminium-plastic tape screens, 5 drainage threads, 6 LSOH anti-flaming inner sheaths, 7 tinned copper wire woven shields, 8 halogen-free and low-smoke flame-retardant polyolefin oversheaths.
Embodiment
As shown in Figure 1, be insulation of LSOH anti-flaming cross-linked polyolefin and sheath nuclear level control cable, comprise seven mutual stranded cores, every core is made up of the cross-linked polyolefin insulating barrier 2 of some copper conductors 1 and copper conductor 1 periphery, at the wrapped polyester belt 3 of the periphery of seven cores, the wrapped aluminium-plastic tape screen 4 of the periphery of polyester belt 3, between polyester belt 3 and aluminium-plastic tape screen 4, be provided with one by the stranded drainage thread 5 of multiply tinned copper wire, the aluminium-plastic tape screen 4 outer LSOH anti-flaming inner sheaths 6 that extrude, the periphery of LSOH anti-flaming inner sheath 6 is provided with tinned copper wire woven shield 7, and the periphery of tinned copper wire woven shield 7 is provided with halogen-free and low-smoke flame-retardant polyolefin oversheath 8.
