Describe a kind of self-supporting cable in international application WO 97/40504, it has around insulated electric conductor
Shielding band, when cable hangs on fixing point, shielding band protects cable effectively.Cable can be equipped with above-mentioned zone
Pipe.International application WO 2004/006272 describes a kind of cable, and it has the shielding band of partially electronically conductive material, this shielding
Band lays along cable in the region between insulated electric conductor and cable sheathing.Conductor wire is whole along it in band
Length and lay and form effective protection to cut off cable voltage when cable is penetrated by conductive body.And, pipe also can cloth
It is placed in this cable.
The cable of the above-mentioned type is highly suitable for their purpose, but if they are equipped with the pipe for optical cable, then
Problem occurs.When manufacturing or process cable, pipe may deform, and this deformation leads to install optical fiber.For example
When cable is hung along cable by suspension equipment or is held in cable end by binding apparatus, it is possible that this
Plant deformation.The cable on embedment ground may be deformed due to stone, and be even placed in the cable in seabed and may stand to make pipe
The power of deformation.Pipe can be made very strong so that it tolerates deformation force.This can have the disadvantages that：Pipe can become very
Firm and all cables would is that rigid and are difficult to process.
