Specific embodiment
A kind of industrial cable proposed by the present invention is described in further detail below in conjunction with the drawings and specific embodiments.Root
According to following explanation and claims, advantages and features of the invention will become apparent from.It should be noted that attached drawing is using very simple
The form of change and using non-accurate ratio, only for the purpose of facilitating and clarifying the purpose of the embodiments of the invention.
The present invention provides a kind of industrial cable, includes successively from the inside to the outside：Waterproof layer, inner restrictive coating 5, enhancement layer 6 and
External sheath layer 7, waterproof layer is interior to include several conductors 1 and several tension gasket for packings 4, and the conductor 1 is surrounding a tension gasket for packing 4 just
Strand of restoring to norm is set, setting tension gasket for packing in gap between conductor 1.
Below with 3x16mm2Further statement in detail is done for conductor to the present invention, referring to Fig. 1, in this cable, packet
Three conductors 1 and several tension gasket for packings 4 are included, three conductors 1 surround a tension gasket for packing 4 knob in a manner of strand of just restoring to norm
Cable is twisted into, tension gasket for packing 4 is set in gap between the conductors, and mixes the outside of setting with tension gasket for packing 4 in conductor 1
A wrapped water blocking tape, and inner restrictive coating 5, enhancement layer 6, outer water blocking layer 7 and external sheath layer 8 are set gradually outside water blocking tape.
Specifically, waterproof layer includes inner waterproofing layer 3 and exterior waterproof coating 7, includes between inner waterproofing layer 3 and exterior waterproof coating 7
