Description

9 core EP actuator cable

Technical field

The utility model relates to field of cables, specifically, relates to a kind of 9 core EP actuator cable.

Background technology

The requirement of progressive let us to security protection of society improves constantly.Requiring that Wireline Data Wireline transmission speed is faster, transmission bandwidth wider while, to fire-resistant communication cable in a fire continued power ability also have more and more higher requirement, the insulated fireproof performance of fire-resistant communication cable is to continued power ability important in its fire.And the insulating material that prior art uses cannot ensure that 9 core EP actuator cable can also keep basic transformation parameter with concrete on fire in a fire.

Utility model content

The technical problem that 1, will solve

The purpose of this utility model is to provide a kind of 9 core EP actuator cable that still can keep basic transformation parameter in a fire with concrete on fire.

2, technical scheme

For achieving the above object, the utility model adopts following technical scheme:

9 core EP actuator cable, comprise cable unit, the first core, the second core, the 3rd core, filled core, packing material, screen and sheath; The first described core, the second core and the 3rd core close-packed arrays, around cable unit, are provided with between the first adjacent core and are respectively equipped with the second core, the 3rd core and filled core; Cable unit, the first core, the second core, the 3rd core and filled core twist together circular, and outside packing material is wrapped up; Described screen is wrapped in the outside of packing material, and described sheath is wrapped in the outside of screen.

Further, described cable unit is by the stranded rounded rear parcel packing material of two filled cores of the identical core of two specifications and core both sides, and the periphery of packing material is thin-walled screen, and the periphery of thin-walled screen is sheath.

Further, the core of the first described core, the second core, the 3rd core and cable unit forms by by conductor and insulating barrier, insulating barrier consistent seal conductor.

Further, described conductor is tin-coated copper wire of annealing flexibly.

Further, the material of described insulating barrier is foam crosslinked polyethylene.

Further, the material of described packing material is plastic adhesive tape.

Further, described screen is woven by tin-coated copper wire of annealing and forms.

Further, the crosslinked polyethylene of the material of described sheath to be model be EM104.

3, beneficial effect

(1) rated voltage for cable of the present utility model is 300V, have low temperature resistant, high temperature resistant grade is high, lightweight, electric property and the distinguishing feature such as mechanical and physical performance is excellent;

(2) conductor of the present utility model have employed annealing tin-coated copper wire flexibly, adds the pliability of cable; Adopt low-smoke halogen-free polyolefin elastomeric material, make the bending force of cable less, increase the pliability of cable, and adopt halogen-free polyolefin elastomeric material, make it have good resistance to wear;

(3) the utility model adopts halogen-free low-smoke flame retardant material, toxic gas and dense smoke is produced hardly when fire occurs, be conducive to the smooth expansion of fire-fighting work, redundant labor transfer, control spreading of fire, more can alleviate the secondary disaster that hydrogen halide causes precision instrument and equipments etc. such as the instrument and meters in surrounding environment;

(4) the utility model adopt sheath and insulating barrier all adopt cross-linking polyethylene materials, double-deck high temperature resistant, the highest high temperature resistant to 110 degrees Celsius, fail safe strengthens, make the fire resistance that cable is higher, there is the transmission characteristic of standard EN more than 50200, substantially constant basic transformation parameter can be kept with concrete on fire in a fire.
