Material is low smoke halogen-free flame-retardant polyolefin.
Each parameter is as shown in table 1 below.
Table 1
Minimum oversheath wall thickness：Minimum oversheath wall thickness >=0.4mm of composite rope；
Separability：The tear edge for meeting 3~15N, is mainly ensured by the wall thickness (0.4mm) of tearing port 9；
Fiber number explanation：The composite rope use is at least 1 light in the access network segment, access network segment butterfly leading in cable
Fibre, but most operators can select twin fiber cable when selecting indoor optical cable, and using one, another is used as spare fibre.
Cable portion performance is as shown in table 2.
Table 2
Cable section performance is as shown in table 3.
Table 3
A kind of production technology of the easily branched type coaxial photoelectric composite rope of platypelloid type, includes the following steps：
Step 1：Tight sleeve layer 6 will be added outside optical fiber 5, optical fiber 5 is fixed, form tight tube fiber 10；
Step 2：Insulating layer 2 will be formed by the extrusion molding that foams outside copper wire, 2 outside of insulating layer uses proof copper-wire braided networking
Cable conductor 11 is made in shape structure；

Step 4：By in step 1 to step 3 cable and optical cable pass through extruding machine 13 carry out sheath extrusion molding；
Step 5：Sheath in step 4 is cooled and shaped, is then drawn through dragger 14,15 take-up of take-up stand is obtained into
Product composite rope.
13 front end of extruding machine is equipped with cable conductor pay off rack 16, fixed pay off rack 17 and aramid yarn pay off rack 18, puts respectively
Cable conductor 11, tight tube fiber 10 and aramid yarn 12 are set, the passive unwrapping wire of tension is passed through；Cable conductor pay off rack 16 is placed on extrusion molding
13 front end center position of machine, fixed pay off rack 17 and 18 coaxial placement of aramid yarn pay off rack.
Technique is cooled and shaped to be cooled down using bosh 19.
The control of temperature
Low-smoke halogen-free flame retardant material temperature control requirement is higher, and temperature is too high to cause flame retardant effect to reduce, the too low Buddhist nun of temperature
Dragon meeting condensation cured causes the blocking of mold.155 DEG C of the fusing point of low-smoke halogen-free material, and to very temperature sensitive, so extruder
The temperature needs of each section gradually rise, and reference temperature is as follows：
| 1st area | 2nd area | 3rd area | 4th area | 5th area | Flange | Head |
| 125 | 136 | 145 | 148 | 155 | 155 | 155 |
Extrusion temperature will according to temperature, go out linear velocity and gel quantity size etc. and appropriately adjust, it is important to note that extruder
The temperature of machine neck, because this is junction, along with having filter plate, strainer, flange chuck etc., heat dissipation area in this region
Greatly, therefore it is difficult to heat in place, is not up to required if heating, it is easy to which the part Halogen material of region formation herein is solid in rigid be switched on
Change, make extruder can not plastic emitting, at this moment screw rod have the danger of fracture.Therefore opportunity neck temperature has just been started or against machine neck both ends
Temperature wants higher 5 DEG C, in favor of heat transfer, 5-10min is kept again after each zone temperatures reach specified value, to ensure at machine neck
Temperature reaches scheduled requirement, not will produce condensation and blocking thus.In addition, screw rod should pay attention to seeing immediately while just startup
Screw rod current instrument is examined, whether abnormal observation electric current is bigger than normal, if electric current is bigger than normal, should shut down in time at this time, and heating temperature is turned up
Or continue to heat.
The effect of strainer
1, granulometric impurity, incipient scorch particle are filtered out；
2, the resistance and counter-pressure for increasing logistics make low-smoke halogen-free material plasticizing evenly；
3, increase pressure, make extrusion uniform flow.
Strainer is 120 mesh aluminium bound edges.Due to being that fluidised form its pressure is little after low smoke and zero halogen high temperature, strainer will not be racked.
It should be appreciated that although this specification is described in terms of embodiments, but not each embodiment only includes one
A independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should will illustrate
As a whole, the technical solutions in the various embodiments may also be suitably combined for book, and forming those skilled in the art can manage
The other embodiment of solution.
