Abstract
The utility model discloses a polyethylene ship power cable, which comprises multiple insulating cores. The multiple insulating cores are stranded and then successively wrapped in a taped covering, a shielding layer, an armor layer and a sheath layer from inside to outside, wherein filling materials are arranged between the insulating cores and the taped covering. Each insulating core comprises a conductor and a three-layer co-extrusion insulating layer wrapping the conductor, wherein the three-layer co-extrusion insulating layer successively comprises a conductor shielding layer, a dry type chemical crosslinked polyethylene layer and an insulation shielding layer from inside to outside. The polyethylene ship power cable disclosed by the utility model not only has general performance of common power cables including electric insulation and anti-electromagnetic interference, but also possesses excellent waterproof, toxic-free, halogen-free and low-smoke performance as well as good machinery performance, which can cope with various external forces such as towing, drawing and impact.
Description
Technical field
The utility model relates to technical field of electric wires and cables, relates in particular to a kind of polyethylene ship power cable.
Background technology
The construction that stimulates cruise in vogue that cruise is spent a holiday, every cruise must be laid the insulated cable more than 1000 kilometers, spread all over full ship.Therefore, the demand of shipboard cable is progressively increasing and is proposing higher performance requirement cheaply.Contact wet environment even may be immersed in the water owing to long-term for the insulated power cable that is applied on the outer boats and ships, possess except needs the general performances such as conventional control cable electrical insulating property, anti-electromagnetic interference, also need to possess performances such as excellent water resistance and nontoxic, low smoke, zero halogen, in addition, also need to possess the favorable mechanical performance, with the test of all kinds of external influence power such as reply towing, tractive, impact.
Summary of the invention
The purpose of this utility model provides a kind of polyethylene ship power cable, except possessing general performances such as conventional control cable electrical insulating property, anti-electromagnetic interference, also possess performances such as excellent water resistance and nontoxic, low smoke, zero halogen, and the favorable mechanical performance, can tackle the test of all kinds of external influence power such as towing, tractive, impact.
Technical solution of the present utility model is:
A kind of polyethylene ship power cable is provided, comprise that many eradication edge cores wrap up twining package tape, screen, armour, restrictive coating after stranded from the inside to the outside successively, be provided with inserts between described insulated wire cores and the twining package tape, described every eradication edge core comprises conductor and is wrapped in the outer three-layer co-extruded insulating barrier of conductor that described three-layer co-extruded structure is followed successively by conductor screen, dry chemical crosslinked polyethylene, insulation shielding from the inside to the outside.
As the further improved polyethylene ship power cable of the utility model, described twining package tape is attached with polyacrylamide for the chemical fibre substrate surface.Polyacrylamide has stronger water-swelling property, so after in moisture enters cable, the coated polyacrylamide in waterstop surface can sharply expand, thereby the filling gap stops the continuation of moisture to be infiltrated.
As the further improved polyethylene ship power cable of the utility model, described inserts is magnesium oxide mineral powder.
As the further improved polyethylene ship power cable of the utility model, described screen is electric barrier paper.The electricity barrier paper can reduce the influence of electrostatic interference effectively, and has characteristics such as cold-resistant, high temperature resistant, acid and alkali-resistance, waterproof.
As the further improved polyethylene ship power cable of the utility model, described armour is braided steel wire stranding armouring.Braided steel wire stranding armouring has not only played the effect that strengthens cable machinery intensity, also cooperates the good electric magnetic shield performance that has realized cable with electric barrier paper.
As the further improved polyethylene ship power cable of the utility model, described restrictive coating is the halogen-free anti-flaming polyolefin sheath.
Polyethylene ship power cable provided by the utility model, except possessing general performances such as conventional control cable electrical insulating property, anti-electromagnetic interference, also possess performances such as excellent water resistance and nontoxic, low smoke, zero halogen, and the favorable mechanical performance, can tackle the test of all kinds of external influence power such as towing, tractive, impact.
Description of drawings
Fig. 1, the structural representation of polyethylene ship power cable provided by the utility model.
1 is insulated wire cores, and 2 is inserts, and 3 is twining package tape, and 4 is screen, and 5 is armour, and 6 is restrictive coating.
Embodiment
In order to deepen understanding of the present utility model, the utility model is done describing in further detail below in conjunction with drawings and Examples, this embodiment only is used for explaining the utility model, does not constitute the restriction to the utility model protection range.
Polyethylene ship power cable as shown in Figure 1, comprise that the edge cores 1 of thoroughly doing away with wrap up twining package tape 3, screen 4, armour 5, restrictive coating 6 after stranded successively, be provided with inserts 2 between described insulated wire cores and the twining package tape 3, described every eradication edge core 1 comprises conductor and is wrapped in the outer three-layer co-extruded insulating barrier of conductor that described three-layer co-extruded structure is followed successively by conductor screen, dry chemical crosslinked polyethylene, insulation shielding from the inside to the outside.
Described twining package tape 3 is attached with polyacrylamide for the chemical fibre substrate surface.Polyacrylamide has stronger water-swelling property, so after in moisture enters cable, the coated polyacrylamide in waterstop surface can sharply expand, thereby the filling gap stops the continuation of moisture to be infiltrated.Described inserts 2 is magnesium oxide mineral powder.Fill magnesium oxide and make cable have excellent fireproof performance, and cost is lower, makes cable product have high cost performance.
Described screen 4 is electric barrier paper.The electricity barrier paper can reduce the influence of electrostatic interference effectively, and has characteristics such as cold-resistant, high temperature resistant, acid and alkali-resistance, waterproof.Described armour 5 is braided steel wire stranding armouring.Braided steel wire stranding armouring has not only played the effect that strengthens cable machinery intensity, also cooperates the good electric magnetic shield performance that has realized cable with electric barrier paper.Described restrictive coating 6 is the halogen-free anti-flaming polyolefin sheath.
