Described insulating layer material adopts silicon rubber.
Described restrictive coating material adopts TPUE.
(1) conductor, copper cash mechanical property depend on material selection and processing technology thereof; The copper stranded conductor flexibility depends on the diameter and the correlative factors such as direction of lay control and twisting pitch of stranded annealed copper wire.The stranded conductor that the copper line diameter is big, its tensile property is good, but flexibility is poor, and not flexible; The stranded conductor that the copper line diameter is little, soft, resistance to bend(ing) is good, but tensile property is poor.Conductor should adopt the 6th kind of copper or the tin-coated copper conductor stipulated among the GB/T3956 to restraint stranded forming in the same way.In order to reduce the bending modulus of stranded conductor, increase the flexibility of cable, further improve the anti-degree of crook of cable, secondly it is stranded to adopt the 6th kind of more soft annealing single round copper wire to restraint strand in the same way,, should adopt stranded tinned wird, tin-coated copper single line smooth surface, activity are good, when cable was crooked, the frictional resistance in the stranded conductor between the tinned wird reduced with restraining force mutually, helped lead and slided and stretch song along unidirectional spiral.
(2) insulating barrier, insulation adopt high tear-proof, high-intensity organic silicon rubber as cable insulation, back and forth deflect required physical and mechanical properties in the hope of bearing.
Silicon rubber is a kind of pliability elastomer preferably.The curl of when free state, crispaturaing, strand is submissive, and intermolecular attraction is little, and surface tension is low, has high compression set resistant performance, low temperature elasticity, high plasticity and special surface self-lubricating, can not adhere to contact material; Not only can under the adverse circumstances of high and low temperature, work, and the influence that changes of radius and corner frequency by bending of the electric property of cable and mechanical performance is less.Adopt silicon rubber to make the insulating barrier of starting loop wheel machine flexible cable, insulated wire cores when cable is crooked in the cable cover(ing) can effectively be moved cunning, disperse and alleviate of the effect of each mechanical stress, make cable avoid causing copper cash overbending and fracture because of mechanical stress concentration to conductor wire core.This can increase the pliability of cable, can increase the anti-bent horizontal of cable again, can reduce the probability of the disconnected core of cable largely.Experiment and operation result show, back and forth deflect test even stand 100,000 times, conductor also do not rupture or core between short circuit, shown that it has the bending resistance of excellence, and enough useful life and economic worth.Therefore, make the cable of insulating barrier with silicon rubber, but some than the occasion of small-bend radius under continuous bend use, has good physical and mechanical property, outstanding to a greater extent hoisting equipment has many incomparable advantages with the security reliability and the using value of cable than other India-rubber cables on performance and function.
Silastic material has good pliability, make the working temperature of cable bring up to 180 ℃ Celsius, improve the voltage-resistent characteristic of product simultaneously, also have very high thermal endurance, excellent cold resistance, excellent electric insulation performance, good aging properties, excellent oil resistance, and nontoxic odorless.It is a kind of desirable hoisting equipment cable insulating coating material.
(3) cable element.As for manufacturing process, the main points of flexible cable are the cabling process of cable core, and a good cabling process can greatly reduce the problem that cable in use produces the core fracture.The main points of cabling process both must keep the unanimity of inner all cores of cable core and composition element tension force, and the internal stress that the tension force inequality is produced when getting rid of any core possibility owing to stranding will produce very big hidden danger to the normal use of cable in the future so.Because cable is under frequent bending, reeling condition, local internal stress can slowly be concentrated to certain point and overstock, and causes flex point, knuckle to cause metal fatigue at last and rupture.This clock phenomenon explanation, the adjustment of laying tension is very crucial, by improving actinobacillus device, the laying tension of insulated wire cores keeps uniformity when guaranteeing stranding, too concentrates a certain core and influences the cable bending property to reduce each core tension force inequality or pulling force.The cable core of emitting like this is tight, rounding.
Filling material should be even, and size should be consistent, makes no any space between cable core, is aided with the extruded type sheath to guarantee that cable core is tight, sheath is evenly fitted.Outer wrapped one or more layers band of cable core is tightened, and prevents that cable core is loose in the laid processes.
(4) screen, shielding adopt copper strips or copper wire shielding.Copper strips shields wrapped Duplication should be not less than 15%, and the copper wire shielding can be adopted zinc-plated or not zinc-plated circular copper wire braiding, and shielding density is greater than 80%.
(5) restrictive coating, sheath adopts TPUE (TPU) material.This material by modification after the low temperature brittleness temperature can reach-65 ℃.By strengthening the soft segment molecule amount and the degree of cross linking, increase pliability, make cable become more soft, TPUE (TPU) material has very superior mechanical performance, combination properties such as low temperature is anti-to be turned round, anti-curved, the moisture-proof of low temperature, cold-resistant, salt spray resistance, oil resistant, UV resistant, and having biodegradable environmental-protecting performance again, is a kind of desirable cold resistant cable clad material.When sheath is extruded, should strengthen the radial pressure of mould, extrude tight, solid with assurance.Jacket surface should be smooth, rounding, color and luster basically identical, and section should not have visible bubble of eyesight and impurity.
Advantage of the present utility model is as follows:
Of the present utility model simple in structure, easily manufactured, have the excellent electric insulation performance, cable intensity is good, advantages of good shielding performance; Low temperature is anti-to be turned round, anti-curved, high temperature resistant, the moisture-proof of low temperature, cold-resistant, salt spray resistance, oil resistant, UV resistant, softness characteristics movably, and cable still can normal mounting lay when subzero 50 spend, and still keeps better elastic and bendability.Simultaneously, can satisfy and keep the cable key property under the environment of weather, hydrolysis or mechanical damage in cold; Environmental protection, having embodied is the theory of low-carbon (LC) society.
Technological advantage:
(1) has the hollow line cored structure, promptly use soft filler and round insulation core stranded, to increase the bending resistance of core;
