Abstract
The utility model relates to a kind of from more cable, and comprise conductor, insulating barrier and sheath, described insulating barrier, sheath are coated on outside conductor from inside to outside successively, are also provided with water-soluble solution expanded polymeric layer between described insulating barrier and sheath; When cable bad is intake, water-soluble solution expanded polymeric layer water-swellable, the space in filled cable, makes the position of repairing and damaging in cable up.Compared with prior art, the utility model has the advantages such as cost is low, safe and reliable, maintenance is convenient.
Description
Technical field
The utility model relates to a kind of cable, especially relates to a kind of from more cable, when the destroyed water inlet of cable cover(ing), seal rapidly, thus teaching display stand makes up, repairs to the position of cable bad.
Background technology
At present, conventional cable is primarily of conductor (communication unit), insulation, packing material, band, metal tape, sheath composition.These cables are mainly used in electric power transfer or distribution, telecommunications, video and transfer of data.
In production, transport, install, between the operating period, these cables may suffer damage, especially when direct-burried, be arranged in tunnel or underground piping, stone of construction and installation instrument, backfill etc., all may cause damage to cable.These damages can be sheaths, also may injure insulating barrier.When moisture penetration is to the insulating barrier damaged, electric leakage will be caused.3 heavy rains in Zhengzhou in 2013, less than the bimestrial time, caused 5 dead 4 wounds, investigation display, reason is all because cable leakage.
The measure of blocking water that current cable adopts is divided into radial water-resisting and longitudinal water-blocking, and basic structure is all adopt waterstop, water blocking yarn or waterproof paste etc.Expand after the shortcoming of waterstop, water blocking yarn is to absorb water, but can not combine, and not have viscosity with insulation, sheath material, and heat resistance is bad, tensile strength is lower.The shortcoming of waterproof paste is that construction and installation are inconvenient, and block-water performance can not meet the requirement that blocks water of cable.
Summary of the invention
The purpose of this utility model be exactly provide to overcome defect that above-mentioned prior art exists that a kind of cost is low, safe and reliable, maintenance is easily from more cable.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of from more cable, comprise conductor, insulating barrier and sheath, described insulating barrier, sheath are coated on outside conductor from inside to outside successively, are also provided with water-soluble solution expanded polymeric layer between described insulating barrier and sheath.
Described conductor is provided with multiple, forms a conductor bundle, and described insulating barrier is coated on outside conductor bundle.
Described conductor is provided with multiple, and described insulating barrier is coated on outside each conductor, forms multiple insulated wire cores, and described water-soluble solution expanded polymeric layer is filled between insulated wire cores.
In described water-soluble solution expanded polymeric layer, the melt index of water-soluble solution expanded polymer is between 50 ~ 500.
Described conductor is by one or more conductors made in copper, tin-coated copper, aluminium.
Described sheath is the expansion cover be made up of PVC, PE or low smoke, zero halogen polyolefin.
Compared with prior art, the utility model has the following advantages:
One, cost is low: due to the inserts mainly bentonite adopted, cheap.
Two, fail safe is high: be provided with water-soluble solution expanded polymeric layer in the utility model cable, and when cable fault is intake, water-soluble solution expanded polymeric layer intumescent filler damaged part, oneself can make up rapidly, can not cause electric leakage.
Three, reliable in function: the utility model water-soluble solution expanded polymer adopts organobentonite and poly polymer, chance water can undergoes rapid expansion, available protecting cable.
Four, installation and repairing is convenient: cable of the present utility model, overall dimension is identical with normal cable, and mounting and installation is the same with normal cable, can not increase extra installation cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is another kind of structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.The present embodiment is implemented premised on technical solutions of the utility model, give detailed execution mode and concrete operating process, but protection range of the present utility model is not limited to following embodiment.
Embodiment 1
As shown in Figure 1, the present embodiment provides a kind of from more cable, comprise conductor 1, insulating barrier 2 and sheath 4, insulating barrier 2, sheath 4 are coated on outside conductor 1 from inside to outside successively, water-soluble solution expanded polymeric layer 3 is also provided with between insulating barrier 2 and sheath 4, wherein, water-soluble solution expanded polymer is a kind ofly substantially meet polymer that water dissolvable expands or for being made up of the mixture of non-water swelling polymer and water-swellable filler substantially, the water-soluble filler expanded of separating of described chance is mainly organic expander soil and poly polymer.
In the present embodiment, conductor 1 is provided with multiple, forms a conductor bundle, and insulating barrier 2 is coated on outside conductor bundle.What insulating barrier 2 adopted is that PVC, XLPE or other insulating material are made.Conductor 1 is by one or more conductors made in copper, tin-coated copper, aluminium.Sheath 4 is the expansion cover be made up of PVC, PE or low smoke, zero halogen polyolefin.In water-soluble solution expanded polymeric layer 3, the melt index of water-soluble solution expanded polymer is between 50 ~ 500, and molecule is from about 1,000,000 ~ 8,000,000.
Conductor 1 adopts conventional wire-drawing equipment to make.
Water-soluble solution expanded polymeric layer 3 is that the polymer that forms with organobentonite and polyethylene is for base-material, add plasticizer, stabilizer and color masterbatch, bentonite content is 25wt%, poly content is 70wt%, the total content of plasticizer, stabilizer and color masterbatch is 5wt%, through blended, at 1500kg/cm
2at pressure and 180 DEG C of temperature, extruding pelletization is formed.
Water-soluble solution expanded polymeric layer 3 adopts following methods to prepare: adopt plastic extruding machine, Extruder temperature is set to a district: 135 DEG C, 2nd district: 150 DEG C, 3rd district: 170 DEG C, 4th district: 180 DEG C, 5th district: 190 DEG C, head: 200 DEG C-210 DEG C, join extrusion molding in plastic extruding machine by above-mentioned raw materials.
When the utility model is when more cable is because of sheath damage and water inflow, water-soluble solution expanded polymeric layer can play water suction and dissolve expansion, automatically damaged part is made up after expansion, cable inside can be invaded further by effective ground resistance sealing, prevent the intrusion because of water from causing insulation to form water tree, thus the useful life of reduction cable, and when insulation has damage, good insulating effect can be played, prevent electric leakage or short circuit, meet the weight increase about 10% ~ 300% that can make cable after the water-soluble packing material separating expansion absorbs water.
