Abstract
The invention relates to a top drive cable which includes four conductors with insulating layers. The four conductors are wrapped with a wrapping tape, an anti-static coating, a sheath and a tegment layer sequentially. A filling rope is arranged between the four conductors and the wrapping tape. The conductors are formed through twisting of a plurality of strands of tin annealed copper wires. The top drive cable is excellent in explosion-proof performance, waterproof performance, anti-static performance, ultraviolet-proof performance and softness performance and is high in mechanical strength.
Description
Technical field
The present invention relates to a kind of cable, specifically top drive cable.
Background technology
Top is driven well system and is mainly comprised supplied by AC/DC electricity system, transmission system (hydraulic pressure, power cable, control cables), PLC/MCC system (the man-machine working face of PLC) composition, traditional top drives that main shaft cable is explosion-proof, waterproof, antistatic, ultraviolet resistance are poor, cause cable often to change, had a strong impact on the efficiency of drilling well.
Summary of the invention
The present invention is intended to overcome the defect of prior art, and a kind of top drive cable is provided, and has excellent explosion-proof performance, water resistance, antistatic performance, anti-uv, softness and high mechanical properties.
In order to solve the problems of the technologies described above, the present invention is achieved in that
A kind of top drive cable, it comprises four conductors with insulation, it is characterized in that: described four conductors are surrounded by band, anti-static coating, sheath and serving outward successively, between four conductors and band, is provided with gasket for packing.
Described top drive cable, is characterized in that: to be that multiply tin annealed copper wire is stranded form described conductor.
The invention has the beneficial effects as follows: there is excellent explosion-proof performance, water resistance, antistatic performance, anti-uv, softness and high mechanical properties, be 3 times of traditional top drive cable useful life useful life, ampacity is larger, security performance is higher, due to long service life, therefore reduced the replacing number of times of cable, improved greatly the production efficiency of drilling well.
Brief description of the drawings
Below in conjunction with drawings and embodiments, the present invention is described in further detail:
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1: a kind of top drive cable, it comprises four conductors 1 with insulation 2, and described four conductors are the 5th class conductor, and its outside is surrounded by successively between band 4, anti-static coating 5, sheath 6 and 7, four conductors 1 of serving and band 4 and is provided with gasket for packing 3; Described conductor 1 forms for multiply tin annealed copper wire is stranded, described band 4 is high-strength high temperature-resistant band, and described sheath 6 is soft type high mechanical properties rubber, and described serving 7 is high mechanical properties rubber strip, conductor 1 maximum operating temperature is 90 DEG C, and cross-sectional area of conductor is 0.5～300mm
2.
The top drive cable that the present invention's ratio uses at present has advantages of the mission life-span long (3 times), loaded current is large, fail safe is higher, the sheath pattern of cable breaks traditions, eliminate the punch-through that cable static produces, be more suitable in the workplace under inflammable, explosive mobile place, climatic environment mal-condition.
Claims (2)
1. a top drive cable, it comprises four conductors with insulation, it is characterized in that: described four conductors are surrounded by band, anti-static coating, sheath and serving outward successively, between four conductors and band, is provided with gasket for packing.
2. top drive cable according to claim 1, is characterized in that: to be that multiply tin annealed copper wire is stranded form described conductor.
