Specific embodiment
As shown in Figures 1 to 4, loss coaxial cables, including inner conductor are successively coated with insulation outside the inner conductor
Layer 2, outer conductor layer 3, drop interlayer, shielded layer 6, inner sheath 8, water absorption layer 9 and oversheath 10.
The outer surface of oversheath 10 is equipped with several axial grooves 101 axially extended, around oversheath 10 between axial groove 101
One week circumferential groove 102 is connected, and when meeting with rainy weather, axial groove 101 and circumferential groove 102 have drainage, rainwater
Ground can be flowed to along axial groove 101 and circumferential groove 102.Axial groove 101 is uniformly distributed on the circumferencial direction of oversheath 10, axial
For the cross-sectional shape of slot 101 to be semicircle, the cross-sectional shape of axial groove 101 and 10 joint 12 of oversheath is arc-shaped, can
To reduce the frictional force of cable in transit, the damage of cable jacket 10 is reduced.The surface of oversheath 10 is equipped with several uniform
The micron-sized protrusion of distribution can be improved the waterproof ability on 10 surface of oversheath similar to the mastoid process structure of lotus leaf surface.Outside
Sheath 10 is low-smoke halogen-free polyolefin material, has high intensity, wear-resistant, high temperature resistant and flame retardant property.
Water-absorption particle 91 is filled with inside water absorption layer 9, water-absorption particle 91 is active carbon particle or porous silica gel particles, when having
When moisture or moisture are invaded inside cable through oversheath 10, water absorption layer 9 can be adsorbed, and prevent moisture or moisture further
The inside for invading cable, can effectively protect the normal use of cable.
Inner sheath 8 is made of pvc material.The presence of duplex sheath enhances the intensity of cable, reduces cable
The damage occurred when bending.Shielded layer 6 is made of tinned copper wire or silver-gilt copper wire material.
