Abstract

The utility model relates to a marine medium-voltage fire-proof power cable. A semiconducting conductor shielding layer is extruded and wrapped on the periphery of a twisting tinning annealing copper conductor of the cable; a fire-proof mica tape is wound and wrapped on the periphery of the semiconducting conductor shielding layer; an insulation layer and a semiconducting insulation shielding layer are extruded and wrapped through the coextrusion of the periphery of the fire-proof mica tape from inward to outward; a metal shielding layer is covered on the outer periphery of the semiconducting insulation shielding layer so as to form shielding insulation core wires; multiple shielding insulation core wires are twisted mutually so as to form a cable core; a halogen-free liner layer is extruded and wrapped on the periphery of the cable core; a tinning copper wire weaving armor layer is covered on the outer periphery of the halogen-free liner layer; and a flame-retardant cross-linking polyolefin outer sheath is extruded and wrapped on the outer periphery of the tinning copper wire weaving armor layer. The cable has a good shielding effect and superior fire-proof performance.

Description

Press fireproof power cable in peculiar to vessel
Technical field
The utility model relates to a kind of power cable, particularly a kind of middle fireproof power cable of pressing peculiar to vessel.
Background technology
Be accompanied by the high-power middle application of piezoelectricity gas equipment on boats and ships and ocean engineering, medium-pressure power cable peculiar to vessel is used more and more.Along with the requirement raising of electrical safety, common flame retardant cable can't satisfy instructions for use, presses for supporting with it fire-resistant midium voltage cable in occasions with higher fireproof requirements.Shield effectiveness to medium-pressure power cable has very high requirement simultaneously.In the market or utilize common flame retardant cable to substitute, or adopt the land to substitute with midium voltage cable, but this two all have inadequacy for ocean engineering and boats and ships.
The utility model content
The purpose of the utility model is, overcomes the problem that exists in the prior art, provides and presses fireproof power cable in peculiar to vessel that a kind of shield effectiveness is good, fire protecting performance is superior.
For solving above technical problem; A kind of peculiar to vessel middle fireproof power cable of pressing that the utility model provided; The periphery of stranded zinc-plated annealed copper conductor is extruded with the semiconductive conductor shield; The periphery of said semiconductive conductor shield is surrounded with fire-resistant isinglass belt, and the periphery of said fire-resistant isinglass belt co-extrusion from inside to outside is extruded with insulating barrier and semiconductive insulation screen, and the periphery of said semiconductive insulation screen is coated with metal screen layer and constitutes the shielding insulation heart yearn; The many mutual stranded cable cores that become of said shielding insulation heart yearn; The periphery of said cable core is extruded with the Halogen laying; The periphery of said Halogen laying is coated with tinned copper wire braiding armour, and the periphery of said tinned copper wire braiding armour is extruded with flame-proof cross-linking polyolefin oversheath.
With respect to prior art; The utility model has been obtained following beneficial effect: the periphery of stranded zinc-plated annealed copper conductor is surrounded with fire-resistant isinglass belt; Improved fire protecting performance, and conductor is coated with three layers of screen, is followed successively by semiconductive conductor shield, semiconductive insulation screen and metal screen layer; Can guarantee shield effectiveness, flame-proof cross-linking polyolefin oversheath also has certain flame retardant effect.
As the preferred version of the utility model, said fire-resistant isinglass belt adopts eclipsed form wrapped, and the wrapped rate of putting up is 20% ~ 40%.
Description of drawings
Fig. 1 is the utility model middle structural representation of pressing fireproof power cable peculiar to vessel.
Among the figure: 1 stranded zinc-plated annealed copper conductor, 2 semiconductive conductor shields, 3 fire-resistant isinglass belts, 4 insulating barriers, 5 semiconductive insulation screens, 6 metal screen layers, 7 Halogen layings, 8 tinned copper wires braiding armour, 9 flame-proof cross-linking polyolefin oversheaths.
Embodiment
As shown in Figure 1; The peculiar to vessel middle fireproof power cable of pressing of the utility model; The periphery of stranded zinc-plated annealed copper conductor 1 is extruded with semiconductive conductor shield 2; The periphery of semiconductive conductor shield 2 is surrounded with fire-resistant isinglass belt 3, and the periphery of fire-resistant isinglass belt 3 co-extrusion from inside to outside is extruded with insulating barrier 4 and semiconductive insulation screen 5, and the periphery of semiconductive insulation screen 5 is coated with metal screen layer 6 and constitutes the shielding insulation heart yearn; The many mutual stranded cable cores that become of shielding insulation heart yearn, the periphery of cable core is extruded with Halogen laying 7, and the periphery of Halogen laying 7 is coated with tinned copper wire braiding armour 8, and the periphery of tinned copper wire braiding armour 8 is extruded with flame-proof cross-linking polyolefin oversheath 9.Insulating barrier 4 can adopt Halogen ethylene-propylene rubber or crosslinked polyetylene insulated layer; Metal screen layer 6 can adopt tinned copper wire braiding or wrapped copper strips.
Except that the foregoing description, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of the utility model requirement.
