Abstract

The utility model discloses an oil-resisting, corrosion-preventing and fireproof marine control cable. In the utility model, each of insulation wire cores is formed by multi-strands of tinned copper conductors, a synthetic mica tape fireproof layer and an irradiation cross-linked polyethylene insulation layer extruded on the fireproof layer. A cable core is formed by twisting insulation wire cores. Cable core gaps are filled with filling layers made of glass fiber. Glass fiber belts wrap the cable core in an overlapping manner and a thermosetting non-halogen low-smoke polyolefin inner sheath is extruded on the cable core. A tinned copper wire shielding armor layer is weaved outside the inner sheath. A thermosetting non-halogen low-smoke polyolefin outer sheath is extruded on the outermost layer of the cable. The oil-resisting, corrosion-preventing and fireproof marine control cable in the utility model has excellent characteristics of corrosion prevention, oil resistance, fire resistance, no halogen, no lead, no fluoride, no alkali and no asbestos.

Description

The oil resistance anticorrosion control cable peculiar to vessel of preventing fires

Technical field:

The utility model relates to a kind of oil resistance anticorrosion control cable peculiar to vessel of preventing fires, and belongs to technical field of electric wires and cables.

Background technology:

Along with the manufacturing high speed development of Chinese vessel, control cable peculiar to vessel will obtain to develop fast as the auxiliary products of boats and ships.Control cable peculiar to vessel is mainly used in the signal transmission of ship control system, is the neural lifeblood of control system on the boats and ships, plays an important role for the normal operation of boats and ships.Because the particularity of control cable peculiar to vessel and key; Present many shipbuilding factory requires to adopt fire prevention, oil resistant, anti-corrosion product for the control system connecting line of critical component; Can operate as normal in order to control system under emergency rating, avoid unnecessary loss.

The boats and ships of China also are in the primary stage with the manufacturing of cable at present; The technical merit and the level of processing that add domestic each cable producer are uneven; And International Maritime Organization has higher requirement to shipboard cable; Not only require boats and ships to have low cigarette, Halogen, flame-retarding characteristic, also will have requirements such as no asbestos, alkali-free, caused certain production difficulty to domestic manufacturer with cable.This just requires producer must break through technology barriers, sets up the R&D team of oneself, develops out the product with independent intellectual property rights, like this, will drive the development of Shipbuilding of China industry, will produce good society and economic benefit.

Summary of the invention:

For overcoming the defective of prior art; The purpose of the utility model is to provide a kind of oil resistance anticorrosion control cable peculiar to vessel of preventing fires; Have excellent oil resistant, fire prevention, characteristic such as anticorrosion, can be widely used in place control system such as boats and ships, oil platform, excellent product performance.

The utility model technical solution problem adopts following technical scheme:

The oil resistance anticorrosion control cable peculiar to vessel of preventing fires; Constitute insulated wire cores by multiply tin-coated copper conductor, synthetic mica tape fireprotection layer and the IXPE insulating barrier that extrudes on said fireprotection layer; Be twisted into cable core by many said insulated wire cores; The packed layer that is made up of glass fiber is filled in the cable core gap; Overlappingly outside said cable core be surrounded with glass fiber tape, be extruded with thermosetting low smoke, zero halogen polyolefin inner sheath, said inner sheath is woven with tinned copper wire shield layer outward, and the outermost layer of cable is extruded with thermosetting low smoke, zero halogen polyolefin oversheath.

Compared with present technology, the beneficial effect of the utility model is embodied in:

1, the utility model conductor adopts 7 strands of stranded tin-coated copper conductor structures, has improved the Corrosion Protection of control cable greatly, guarantees that simultaneously cable keeps excellent electric property in running.

2, fireprotection layer adopts synthetic mica tape wrapped in the utility model, and its temperature resistant grade reaches 1000 ℃, and promptly under 1000 ℃ of flame conditions, cable can normally move 90 minutes, guarantees the normal operation of various control system, reduces unnecessary loss.

3, IXPE is after electron irradiation is crosslinked in the utility model, and mechanical performance improves greatly, guarantees that cable has excellent mechanical performance.Serviceability temperature reaches 125 ℃ simultaneously, compares with the general control cable, and rise appreciably useful life.

4, the utility model adopts the braiding tinned copper wire as the shield layer, not only plays the effect of excellent shielding, and has improved the bending property of cable greatly, has effectively protected the damage of inner sheath simultaneously, improves the useful life of cable.

5, extruding the inside and outside sheath of thermosetting low smoke, zero halogen polyolefin in the utility model is a kind of novel environment friendly material; Behind electron irradiation; Serviceability temperature reaches 105 ℃; Have excellent anticorrosion, oil resistant, fire-retardant, Halogen, unleaded, floride-free, alkali-free, no asbestos characteristic simultaneously, satisfy the instructions for use of control cable peculiar to vessel fully.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Label among the figure: 1 conductor, 2 fireprotection layers, 3 insulating barriers, 4 packed layers, 5 glass fiber tapes, 6 inner sheaths, 7 armours, 8 oversheaths.
