Preferably, the screen layer is followed successively by foil shielding layer and woven shield inside-out.
Preferably, the outer belting layer is cable paper band, is coated on by vertical bag or in a manner of having a swollen head outside the screen layer.
Preferably, the sheath is made using TPE-S types thermoplastic elastomer (TPE).
Beneficial effects of the present invention：
The present invention includes conductor, interior belting layer, insulating barrier, tensile layer, screen layer, outer belting layer and sheath, described to lead
Body, interior belting layer, insulating barrier, tensile layer, screen layer, outer belting layer and sheath are radially set from inside to outside successively.Interior outsourcing
The setting of belt makes conductor and braiding more rounding, compact, can effectively avoid that conductor is loose or ellipse causes hydraulic performance decline, shadow
The high pressure resistant effect of cable is rung, tensile layer can increase the tensile strength of electric wire, while realize the indehiscent effect of acute angle bending,
The setting of screen layer has very strong shield effectiveness, more can effectively resist low-frequency disturbance.
