Description

A kind of waterproof frequency conversion tension power cable

Technical field

The utility model belongs to field of cables, relates in particular to a kind of waterproof frequency conversion tension power cable.

Background technology

At present, this product is mainly used in the vibratilities such as bridge by force and the high field of the frequency of paddling, such conventional electric wire mainly adopts silver-plated copper core conductor at present, for the strong field of the vibratilities such as bridge, and the requirement of the high field of the frequency of paddling to the shockproof pull resistance of cable, develop the utility model cable product, can meet certain needs.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of waterproof frequency conversion tension power cable.

The utility model takes following technical scheme to realize: a kind of waterproof frequency conversion tension power cable, it mainly comprises tin-coated copper flexible conductor cable core, copper conductor cable core, copper-clad steel band armour, chloroprene rubber sheath layer, teflon insulation layer, copper strip shielding layer and copper strips armouring polyolefin jacket layer, described tin-coated copper flexible conductor cable core and copper conductor cable core are respectively two groups, be extruded in symmetrically copper-clad steel band armour inner, four groups of cable core inside are all extruded with an aluminium wire heating wire, described tin-coated copper flexible conductor cable core is by a tin-coated copper flexible conductor, be wrapped in the plumbous cover of one deck alloy screen outside tin-coated copper flexible conductor, one deck nickel strap armour and the outermost butyronitrile insulating barrier that are wrapped in outside the plumbous cover of alloy screen form, described copper conductor cable core is by a copper conductor, the ethylene propylene rubber insulated layer of one deck and the outermost low-smoke halogen-free polyolefin restrictive coating that are wrapped in outside copper conductor form, outside described copper-clad steel band armour, wrap up one deck chloroprene rubber sheath layer, outermost layer is copper strips armouring polyolefin jacket layer.

Between described chloroprene rubber sheath layer and teflon insulation layer, be extruded with a copper wire drainage thread, between described teflon insulation layer, copper strip shielding layer and copper strips armouring polyolefin jacket layer, be extruded with a steel band tension silk.

The utlity model has in sum following beneficial effect: feature of the present utility model is good water-proof effect, and pull resistance is strong, also have the feature that flexibility is good, screen is thicker, has excellent shield effectiveness, easy for installation, meets installing and using of bridge place.

Accompanying drawing explanation

Fig. 1 is the utility model cross-sectional structure schematic diagram;

Wherein: 1, tin-coated copper flexible conductor cable core; 2, copper conductor cable core; 3, copper-clad steel band armour; 4, chloroprene rubber sheath layer; 5, teflon insulation layer; 6, copper strip shielding layer; 7, copper strips armouring polyolefin jacket layer; 8, copper wire drainage thread; 9, steel band tension silk; 10, aluminium wire heating wire.

Embodiment

As shown in Figure 1, a kind of waterproof frequency conversion tension power cable, it mainly comprises tin-coated copper flexible conductor cable core 1, copper conductor cable core 2, copper-clad steel band armour 3, chloroprene rubber sheath layer 4, teflon insulation layer 5, copper strip shielding layer 6 and copper strips armouring polyolefin jacket layer 7, described tin-coated copper flexible conductor cable core 1 and copper conductor cable core 2 are respectively two groups, be extruded in symmetrically copper-clad steel band armour 3 inside, four groups of cable core inside are all extruded with an aluminium wire heating wire 10, described tin-coated copper flexible conductor cable core 1 is by a tin-coated copper flexible conductor, be wrapped in the plumbous cover of one deck alloy screen outside tin-coated copper flexible conductor, one deck nickel strap armour and the outermost butyronitrile insulating barrier that are wrapped in outside the plumbous cover of alloy screen form, described copper conductor cable core 2 is by a copper conductor, the ethylene propylene rubber insulated layer of one deck and the outermost low-smoke halogen-free polyolefin restrictive coating that are wrapped in outside copper conductor form, outside described copper-clad steel band armour 3, wrap up one deck chloroprene rubber sheath layer 4, outermost layer is copper strips armouring polyolefin jacket layer 7.

Embodiment: be extruded with a copper wire drainage thread 8 between chloroprene rubber sheath layer 4 and teflon insulation layer 5.

Between described teflon insulation layer 5, copper strip shielding layer 6 and copper strips armouring polyolefin jacket layer 7, be extruded with a steel band tension silk 9.

Further, conductor is mainly tin-coated copper flexible conductor and copper conductor, is all to make through stranded, identical with the 5th kind or the 6th kind of copper conductor diameter, and cross-sectional area of conductor is less than 15 mm ², it is once stranded that conductor adopts, and four groups of conductor cable cores distance is between any two controlled within the scope of 2-3mm.

Further, this cable permission operational environment maximum temperature is 80 ℃; The permission bending radius of this cable is the outside diameter of cable 10 times.

The above is the utility model embodiment, and the equivalence of doing according to structure, feature and principle described in the utility model application range therefore all changes or modifies, and is included in the utility model patent claim.
