Abstract
The utility model relates to an ethylene-propylene insulated elastomer sheath flat cable with rated voltage of 15 kV and less than 15 kV. It extrudes a conductor shielding layer, an insulating layer and an insulating shielding layer on a single tin plating soft copper conductor in the way of three-layer co-squeeze. The two shielding layers all adopt a cross-linking type EVA material, and the insulating layer adopts a tree resistance soft medium pressure ethylene-propylene rubber material. The insulating shielding layer is covered with a layer of winded semi-conductive layer. The winded semi-conductive layer is knitted with a layer of tin plating copper wire braid. The tin plating copper wire braid is lapped with a layer of winded semi-conductive layer composed core. Many roots of the core are covered with a layer of over-sheath made of an elastomer material after juxtaposition. The utility model has many characteristics such as obviously enhanced soft property, good bending property, environmental change resistance, tree resistance, use of moving and winding time after time, space saving, etc.
Description
Affiliated technical field
The utility model relates to a kind of rated voltage 15kV and the following second third insulating elastomer sheath flat cable, belongs to technical field of electric wires and cables.
Background technology
At present, known rated voltage is that 15kV and following cable are crosslinked polyetylene insulated pvc sheath circle cables, and this cable bending property is poor, and water treeing resistance performance is poor, and environmental resistance is poor, can only fixedly lay, and can not move use, and it is big to take up room.Because of this cable by many stranded the forming of core, especially can not circumnutate repeatedly, otherwise gently then core rise and turn round, heavy then conductor twists off.
Summary of the invention
The purpose of this utility model provides rated voltage 15kV and the following second third insulating elastomer sheath flat cable that a kind of bending radius is little, water treeing resistance performance good, environmental resistance is good, it is little to take up room, can move and can circumnutate repeatedly and use.
The technical solution of the utility model is: it is made up of many zinc-plated soft copper conductors, conductor shield, insulating barrier, insulation screen, semi-conductive tape lapping layer, tincopper fuse wire braided armor, semi-conductive tape lapping layer and oversheaths.On single zinc-plated soft copper conductor, adopt three-layer co-extruded mode evenly to extrude conductor shield, insulating barrier, insulation screen.At the peripheral wrapped one deck semi-conductive tape lapping layer of insulation screen, braiding one deck tincopper fuse wire braided armor on lapping layer, wrapped again one deck semi-conductive tape lapping layer is formed single core outside tincopper fuse wire braided armor, then many above-mentioned cores is arranged in parallel and extrudes oversheath thereon.Conductor shield and insulation screen adopt cross-linking type EVA material to form, and this insulated with material resistance is little and second third insulated combination is tight.Insulating barrier adopts presses the ethylene-propylene rubber material to form in the softness of water-fast tree, this material diminishes Cable Bending Radius, and water treeing resistance performance improves.Lapping layer is made by semiconductive material.Oversheath is made by elastomeric material, and this material resistance to bend(ing) can strengthen.The conductor structure of selecting for use circumnutates cable repeatedly in moving not fragile yet.
Owing to adopted technique scheme, the softness of cable is obviously improved, and had good bending property, anti-environmental change, water-fast tree, removable and can circumnutate repeatedly and use and save characteristics such as space.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1, zinc-plated soft copper conductor, 2, conductor shield, 3, insulating barrier, 4, insulation screen, 5, the semi-conductive tape lapping layer, 6, tincopper fuse wire braided armor, 7, the semi-conductive tape lapping layer, 8 oversheaths.
Embodiment
In embodiment as shown in the figure, form conductor 1 with three zinc-plated soft copper conductors, on the surface of every conductor 1, extrude conductor shield 2, insulating barrier 3 and insulation screen 4 successively in three-layer co-extruded mode.Conductor shield and insulation screen are all selected cross-linking type EVA material for use.Insulating barrier is selected for use and is pressed the ethylene-propylene rubber material to form in the softness of water-fast tree.Lapping layer selects for use semiconductive material to be made.Wrapped one deck semi-conductive tape lapping layer 5 on insulation screen 4.Braiding one deck tincopper fuse wire braided armor 6 outside semi-conductive tape lapping layer 5.Wrapped again one deck semi-conductive tape lapping layer 7 is formed single core on tincopper fuse wire braided armor 6.Coat one deck oversheath 8 in the back side by side at three above-mentioned cores, oversheath is made by elastomeric material.
Claims (1)
1, a kind of rated voltage 15kV and the following second third insulating elastomer sheath flat cable, it is with three-layer co-extruded mode coating conductor screen on single zinc-plated soft copper conductor, insulating barrier, insulation screen, at the peripheral wrapped semi-conductive tape lapping layer of insulation screen, on the semi-conductive tape lapping layer, weave tincopper fuse wire braided armor, wrapped semi-conductive tape lapping layer is formed core on tincopper fuse wire braided armor, on above-mentioned many cores, coat one deck oversheath, it is characterized in that: conductor shield and insulation screen all select for use cross-linking type EVA material to form, insulating barrier adopts presses the ethylene-propylene rubber material to form in the softness of water-fast tree, lapping layer is made by semiconductive material, many cores coat one deck oversheath in the back side by side, and this oversheath is made by elastomeric material.
