Abstract
The utility model discloses a waterproof power cable and relates to a cable, which comprises a cable core and a protective sleeve coating the cable core. A filling layer is arranged between the protective sleeve and the cable core. The filler layer is a rubber layer. The cable core is formed by stranding three insulated wire cores. The insulated wire core comprises a conductor and an insulated layer coating the conductor. The insulated layer has a three-layer composite structure, that is, sequentially from inside to outside an organic insulated layer, a galvanized steel strip armored layer and a water blocking tape layer. The protective sleeve has a three-layer composite structure, that is, sequentially from inside to outside a polyethylene lining layer, a waterproof layer and an outer sheath layer. The outer sheath layer is a double-sided plastic coated embossed steel strip. The waterproof power cable has the advantages of simple structure, good waterproof performance, good security and reliability and strong practicability.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of waterproof power cable.
Background technology
Fast development along with power industry, data communication industry, urban track traffic industry etc., the security reliability that is used in the electric equipments such as subway, nuclear power station, market and hospital requires more and more higher, therefore all trades and professions are more and more higher to the requirement of cable, in use, to avoid not only that cable is mechanically damaged, insulation harm and ageing of insulation are rotten etc., also to avoid humidified insulation, i.e. waterproof.Under normal conditions, cable often is laid in the comparatively moist environment such as ground, because the permeability of cable sheath material, perhaps cable cover(ing) is by mechanical damage, and it is inner that water has entered cable, and interior formation water tree causes insulating, finally cause cable insulation to puncture, greatly shorten the useful life of cable, even caused the electric power shipping accident, caused serious harm for the country and people's lives and properties.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of waterproof power cable, and is simple in structure, and water resistance is good, and is safe and reliable, very practical.
The technical solution of the utility model is: a kind of waterproof power cable, comprise cable core and be wrapped in the outer protective sleeve of cable core, be provided with packed layer between protective sleeve and the cable core, described packed layer is rubber layer, described cable core thoroughly does away with by three that the edge core is stranded to be consisted of, described insulated wire cores is made of the conductor insulating barrier outer with being wrapped in conductor, described insulating barrier is three-layer composite structure, it is followed successively by from inside to outside: organic insulator, galvanized steel strip armour and water blocking tape layer, described protective sleeve is three-layer composite structure, and it is followed successively by from inside to outside: the polyethylene liner layer, watertight composition and external sheath layer; Described external sheath layer is double plastic-coated embossing steel band.
As preferably, described organic insulator adopts polyether sulfone to extrude material and makes.
As preferably, described watertight composition is aluminium-plastic tape.
The beneficial effects of the utility model are: be provided with water blocking tape layer in the insulating barrier of the present utility model, be provided with watertight composition in the protective sleeve, water blocking tape layer is by the polyester fiber woven cloths and high-absorbent material is compound makes.Watertight composition is aluminium-plastic tape.Greatly improved the water resistance of cable.The packed layer that organic insulator, polyethylene liner layer and rubber are made has further improved water resistance of the present utility model.The utility model is simple in structure, and water resistance is good, and it is inner to prevent effectively that moisture from immersing cable, not only cable is played the protective effect of arriving very much, also can prolong the useful life of cable, is particularly suitable for being applied to wet environment, very practical.
