Abstract
The invention discloses a cable for a coal mine. The cable comprises a copper wire inner core (1). The outer surface of the copper wire inner core (1) is coated with an insulating rubber layer (2). A protection sleeve (3) is arranged outside the insulating rubber layer (2) in a sleeved mode. An outer layer sleeve (4) is arranged outside the protection sleeve (3) in a sleeved mode. The surface of the outer layer sleeve (4) is provided with a plurality of hoop sleeves (5) in a sleeved mode.
Description
Technical field
The present invention relates to a kind of coal mine cable.
Back of the body background technology
The cable resistance to wear of current underground mine use is poor, and easily damaged after long-time use and water soaking, therefore useful life is shorter.
Summary of the invention
The invention provides a kind of coal mine cable, its long service life, and also resistance to wear is relatively good.
The present invention has adopted following technical scheme:
oneplant coal mine cable, it comprises copper wire inner core, is coated with insulation glue-line at the outer surface of copper wire inner core, has protective sleeve at insulation glue-line overcoat, has outer cover in the outer cover of protective sleeve, has some cuffs at the surperficial cover of skin cover.
Described insulation glue-line is layer of polyurethane.Described protective sleeve is silica gel sheath.Described skin cover is pvc sheath.Described cuff is PVC insulation cuff.
The present invention has following beneficial effect: adopted after above technical scheme, the present invention has adopted protective sleeve and outer cover, can realize like this double shielding, the useful life of effectively improving cable, wear prevention.The present invention is provided with cuff, and cuff is PVC insulation cuff, so not only solid wear-resisting, and easy to use, long service life.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
