Paver cable
Technical Field
The utility model relates to the technical field of cables, in particular to a paver cable.
Background
The paver is a special machine for paving asphalt mixture and other grading materials, uniformly paving the mixed asphalt mixture (asphalt concrete or black granules) on a prepared roadbed or base layer according to certain technical requirements (thickness and cross section shape), and carrying out preliminary tamping and leveling. The working environment of the paver cable is between 100 ℃ and 140 ℃, the paver cable is frequently moved, the existing paver cable mainly depends on an inlet, the existing paver cable needs to be frequently replaced, and the problems of aging and embrittlement, conductor breakage and the like are easy to occur.
Disclosure of utility model
In view of the above, the utility model provides a paver cable, which aims to solve the problems that the existing paver cable is easy to age and crack and the conductor is easy to break.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
The utility model provides a paver cable, includes by the stranding of many cable cores, inner sheath, shielding layer, oversheath and insulating layer is constituteed, the cable core includes conductor and insulating layer, and the insulating layer adopts high temperature resistant and extremely soft platinum silicone rubber to extrude and forms. The inner sheath is extruded outside the cabling, the shielding layer is woven outside the inner sheath, the outer sheath is extruded outside the shielding layer, and the heat insulation layer comprises a quartz wire weaving layer and a fluorine silicone resin paint coating. The quartz wire has high temperature resistance and heat insulation capacity, and the fluorosilicone resin paint has heat insulation and heat reflection capacities, so that the heat insulation capacity of the cable is improved by combining the high temperature resistance and the heat insulation capacity.
Preferably, the conductor is formed by twisting a plurality of tinned copper wires, and the twisting pitch is 8-10 times.
Preferably, the inner sheath is extruded by platinum silicone rubber, and the extrusion thickness is 0.5mm. The platinum silicone rubber has high temperature resistance and good ageing resistance.
Preferably, the shielding layer is braided by tinned copper wires, so that the shielding and tensile capabilities of the cable can be improved, and the braiding density is not less than 80%.
Preferably, the outer sheath is formed by extruding platinum silicone rubber, and the extrusion thickness is 0.5mm.
Preferably, the weaving density of the quartz wire weaving layer is not less than 70%.
Compared with the prior art, the utility model has the beneficial effects that:
The cable of the paver adopts the platinum silicone rubber, has stronger ageing resistance than the common silicone rubber, is not easy to decompose at high temperature, and ensures long-term effective use. The conductor twisting pitch and the cabling twisting pitch are dense, so that the whole cable is soft enough and is suitable for frequent bending. The combination of nonmetallic braiding and the fluorosilicone resin paint coating is adopted, so that heat is effectively isolated, and the cable can be used for a long time.
