The cable that the large tunnel full advance coordinative composition of equipments such as shield machine use is referred to as cable for shield machine, because its operational environment is special, require cable have bending radius little, frequently can move torsion, meet wear-resisting, oil resistant, softness, tension, anti-tear, the low temperature resistant and more and more high requirement of electric pressure.Cable for shield machine must meet little, the frequent mobile basic demand reversed of Cable Bending Radius under rated voltage 8.7/15kV.Because shield machine is used in tunnel, mountain region, sea (river) tunnel, the end and other subterranean tunnel operations, environment is changeable, severe, and the special cable of China dependence on import always, expensive for this reason.Existing many cable producers start development & production at present, but it is flexible poor to there is cable, the problems such as electric pressure is on the low side, fault is many.Publication number is the application for a patent for invention open " a kind of shield machine rubber sleeve flexible cable " of CN104361927A, and the equal neoprene of the inner sheath of this patent application, oversheath is formed, and neoprene cost is higher, and material is not easily bought.
Utility model content
The purpose of this utility model is to provide a kind of high voltage and resists cold cable for shield machine, improves the serviceability of cable for shield machine, reduces the cost of cable for shield machine, extends the useful life of cable for shield machine.
The technical solution of the utility model is: high voltage resists cold cable for shield machine, comprise master core, wire core, outer shell structure, master core comprises master core conductor, conductor shield, insulating barrier and insulation screen, and wire core comprises wire core conductor and wire core coating layer.Cable for shield machine is by three master cores twisted synthesizing cable together, and three wire core are placed in the cylindrical gap after master core is stranded, and three wire core are in the distribution of cylindrical gap uniformity, and the outside of master core and wire core stranding is provided with two-layer belting layer.The center clearance of three master cores is provided with center-filled thing, and master core, gap between wire core and band reinforced layer are provided with cylindrical filler.Outer shell structure comprises inner sheath, reinforced layer and oversheath, and inner sheath, reinforced layer and oversheath are arranged from inside to outside successively.
Cylindrical filler and center-filled thing are semiconducting rubber.The material of inner sheath and oversheath is chlorinated polyethylene rubber.Reinforced layer is the wrapped braiding reinforced layer of fibrage reinforced layer, metal knitted reinforced layer or metal.Master core conductor and wire core conductor are multiply synnema soft copper conductor lay configuration in the same way, and the material of insulating barrier is ethylene propylene diene rubber.
Master core conductor, wire core conductor employing multiply synnema soft copper conductor is stranded in the same way, pitch multiple proportions is not more than 14 times, and laying up pitch multiple proportions is not more than 9 times, makes cable have enough bending properties.Ethylene propylene diene rubber cured properties and heat-resistant air aging property good, GB/T12706 and T818-2009 standard can be met.Inner sheath, oversheath are formed by chlorinated polyethylene rubber, instead of expensive chloroprene rubber sheathing compound cable.Chlorinated polyethylene rubber has good high flame retardant, high impart tear, and performance index are higher than MT818-2009 standard-required, meets cable for shield machine Special use environment.Make center-filled thing and foreign aid's filler with semiconducting rubber, add cable pliability and stability.
The utility model high voltage cable for shield machine material that resists cold is easy to buy, and reduces production cost, improves the serviceability of cable for shield machine, meet the instructions for use of cable for shield machine under bad working environments condition, be conducive to extending useful life of cable for shield machine.
