Abstract

The invention discloses a water-proof, variable-frequency and tensile power cable which mainly comprises two tinned copper flexible conductor cable cores, two copper conductor cable cores, a copper-clad steel tape armor layer, a neoprene sheath layer, a polytetrafluoroethylene insulating layer, a copper tape shielding layer and a copper tape armor polyolefin sheath layer, wherein the tinned copper flexible conductor cable cores and the copper conductor cable cores are uniformly and symmetrically extruded in the copper-clad steel tape armor layer; the neoprene sheath layer is wrapped outside the copper-clad steel tape armor layer; the copper tape armor polyolefin sheath layer is arranged on an outermost layer; and a drainage wire and a tensile wire are arranged in the cable. The cable has the characteristics that the cable is good in water-proof effect, high in tensile property, good in flexibility, thicker in shielding layer, excellent in shielding effect and convenient to mount, and meets mounting and use of a bridge place.

Description

A kind of waterproof frequency conversion tension power cable

Technical field

The invention belongs to field of cables, relate 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 shockproof pull resistance of the high field of the frequency of paddling to cable, develop cable product of the present invention, can meet certain needs.

Summary of the invention

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

The present invention 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 inside, 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, be wrapped in one deck nickel strap armour and outermost butyronitrile insulating barrier composition outside the plumbous cover of alloy screen, described copper conductor cable core is by a copper conductor, be wrapped in the ethylene propylene rubber insulated layer of one deck and outermost low-smoke halogen-free polyolefin restrictive coating composition outside copper conductor, 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 present invention has following beneficial effect in sum: feature of the present invention is good water-proof effect, and pull resistance is strong, also has the feature that flexibility is good, and screen is thicker, has excellent shield effectiveness, easy for installation, meets installing and using of bridge place.
