Abstract
Provided is a special cable for a port crane. The cable core is composed of a plurality of wire cores and a central reinforcing rib. A shielding layer formed by extrusion moulding of a semiconductive material wraps the cable core. A filling layer is arranged between the shielding layer and the cable core. A fiber braid layer and an outer sheath made of a thermoplastic elastomer material are arranged outside the shielding layer in sequence. According to the utility model, the stretch resistance and the extrusion resistance of the cable are improved, and the cable is soft, wear-resistant, cold-resistant, waterproof and electromagnetic interference-resistant, so that the cable is suitable to be used outdoors.
Description
Technical field
The utility model belongs to private cable technical field, and being specifically related to is harbour driving private cable.
Background technology
At present, along with automatic technology is more and more universal in each occasion, increasing field is used driving to realize automation, cable must adapt to the environment of driving operation as control line or electrical lead, the cable of existing harbour driving use, after operation a period of time, usually there will be the phenomenon of conductor break, sheath cracking, cable is cold-resistant, wear-resisting, tension, anti-extrusion Performance Ratio are poor; Cause cable needs often to be changed, caused great waste, affected production efficiency.
Summary of the invention
The deficiency that cable tension, anti-extrusion performance are poor and sheath ftractures of using in order to overcome the driving of existing harbour, the utility model provides a kind of harbour driving private cable, this harbour driving private cable has improved tension, anti-extrusion performance, and there is softness, wear-resisting, cold-resistant, fire resistance characteristic, appropriate cable is frequently subject to friction, stretches, trembles with fear and freeze in outdoor application, and the while is simple in structure and cost is low.
The utility model solves the technical scheme that its technical problem adopts: the core of harbour driving private cable is comprised of tinned copper wire wrap insulate layer, the center reinforcement that cable core is comprised of several wire core and wire material forms, the screen of cable core outer wrapping semiconductive material extrusion moulding, it between screen and cable core, is packed layer, screen is outward fiber braiding layer, fiber braiding layer is oversheath outward, and oversheath is made by thermoplastic elastic material.
The center reinforcement of wire material composition increases the tensile property of cable.The oversheath that thermoplastic elastic material is made makes cable have high strength, high resilience, is more suitable for using in driving is upper.Screen plays anti-electromagnetic interference and eliminates faradic effect.Fiber braiding layer strengthens the tearing toughness of sheath.
Beneficial effect of the present utility model is; it uses protection multilayer structure, has improved cable tension, anti-extrusion performance, and has softness, wear-resisting, cold-resistant, waterproof, anti-emi characteristics; make cable be adapted at outdoor application, the while is simple in structure and cost is low.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. tinned copper wires in figure, 2. insulating barrier, 3. center reinforcement, 4. packed layer, 5. screen, 6. fiber braiding layer, 7. oversheath.
Embodiment
In Fig. 1, the core of harbour driving private cable is comprised of tinned copper wire 1 wrap insulate layer 2, the center reinforcement 3 that cable core is comprised of several wire core and wire material forms, the screen 5 of cable core outer wrapping semiconductive material extrusion moulding, it between screen 5 and cable core, is packed layer 4, screen 5 is outer is fiber braiding layer 6, and fiber braiding layer 6 is outer is oversheath 7, and oversheath 7 is made by thermoplastic elastic material.
