Abstract

The utility model relates to an air-blowing micro-cable with a low friction, and belongs to the technical filed of communication optical cable product manufacturing. The air-blowing micro-cable comprises a center reinforcement element, a PBT loose pipe, a cable core, cable paste, a polyethylene internal sheath layer, and a silicon material lubricating layer, wherein optical fibers are disposed in the PBT loose pipe, and the PBT loose pipe is filled with fiber paste; the PBT loose pipe is stranded on the center reinforcement element through an SZ stranding method; a cable core is manufactured outside the PBT loose pipe, the interval between the center reinforcement element of the cable core and the PBT loose pipe is filled with the cable paste, and the polyethylene internal sheath layer and the silicon material lubricating layer are squeezed outside the cable core through a squeezing technology. An external sheath layer of the air-blowing micro-cable employs a low-friction silicon material lubricant, so that the friction between micro-cables is reduced greatly. The air-blowing micro-cable is small in external diameter and light in weight, with which, the air-blowing distance in air-blowing construction is made longer, and the construction efficiency is improved, and the problems of big friction factor by employing high density polyethylene material as an external sheath layer, short air-blowing distance, and high manufacturing cost are solved.

Description

A kind of low friction air-blowing micro-cable

Technical field

The utility model relates to a kind of low friction air-blowing micro-cable that is applicable to air-blown installation in microtubule, belongs to communications optical cable product manufacturing technology field.

Background technology

Air-blowing micro-cable is because the features such as its external diameter is little, lightweight, easy construction are widely used in existing communication network.At present, air-blowing micro-cable generally adopts high-density polyethylene material as its serving, because high density polyethylene has relatively large friction factor, in the time carrying out air-blowing construction, optical cable advance resistance is relatively large, has limited the air-blowing distance of optical cable, operating efficiency is low, and cost is relatively high.

Summary of the invention

The purpose of this utility model is, providing a kind of is made up of the optical fiber loose tube, central reinforce member, bundle yarn, cable cream, polythene inner and the low friction silicon materials lubricating layer that are filled with fine cream, have air-blowing distance, low cost of manufacture, is applicable to the low friction air-blowing micro-cable of air-blown installation.

The utility model is to realize by the following technical solutions above-mentioned purpose:

A kind of low friction air-blowing micro-cable, it is by central reinforce member, PBT pine sleeve pipe, cable core, cable cream, polythene inner and silicon materials lubricating layer composition, in PBT pine sleeve pipe, optical fiber is housed and is filled with fine cream, it is characterized in that, on central reinforce member, there are 4～12 PBT pine sleeve pipes by the stranded mode of SZ is stranded, 4～12 PBT pine cover tube outsides form cable core after adopting and pricking the binding of yarn intersection, during institute between central reinforce member in cable core and PBT pine sleeve pipe is gapped, be filled with cable cream, cable core outside is by disposable polythene inner and the silicon materials lubricating layer of being extruded with of expressing technique.

The utility model beneficial effect is compared with prior art:

This low friction air-blowing micro-cable serving adopts solid, permanent low friction silicon materials lubricant, has greatly reduced the frictional resistance between micro-cable and microtubule; And this low friction air-blowing micro-cable external diameter is little, lightweight, in the time that air-blowing is constructed, make micro-cable air-blowing distance longer, construct convenient, improve operating efficiency, save construction cost.Solved existing air-blowing micro-cable and adopted high-density polyethylene material larger as serving friction factor, in the time carrying out air-blowing construction, optical cable advance resistance is larger, and air-blowing distance is short, and operating efficiency is low, the problem that manufacturing cost is higher.
