Abstract
The invention provides a low-voltage cable filling method, which comprises the following steps of: melting paraffin at high temperature; making a bundled cable pass through the melted paraffin; performing water-cooling on the cable; and squeezing the sheath of the cable. By the low-voltage cable filling method, the problem that a small- section and multi-core cable cannot be filled circularly and neatly in the prior art is solved; and the low-voltage cable filling method has the advantages of simple process and low cost, and the cable can be filled circularly and neatly.
Description
Technical field
The present invention relates to the manufacturing of low-voltage cable, particularly relate to a kind of low-voltage cable fill method.
Background technology
The wires and cables industry of China all is to adopt polypropylene to tear nettle to guarantee the rounding of cable outward appearance to the filling of low-voltage cable now.Because the polypropylene material price is not high, its heatproof characteristic adapts with the insulating material of cable again, can meet the national standard requirement of product, therefore extensively adopts polypropylene material to fill.But adopt this material that a serious technical problem is arranged, the small bore multicore cable cannot be filled out rounding, is difficult to satisfy requirement of client.We have invented a kind of new low-voltage cable fill method for this reason, have solved above technical problem.
Summary of the invention
It is simple to the purpose of this invention is to provide a kind of technology, with low cost, and cable is filled the low-voltage cable fill method of rounding.
Purpose of the present invention can realize by following technical measures: the low-voltage cable fill method, and this low-voltage cable fill method comprises the paraffin high temperature melting; The cable that stranding is good passes through from this paraffin of fusing; This cable is carried out water cooling; And the oversheath that pushes this cable.
Purpose of the present invention also can realize by following technical measures:
This low-voltage cable fill method also comprises, after the step of this cable that stranding is good process from the paraffin of fusing, with the laying up diameter close mould of this cable by a secondary endoporus and this cable, removes unnecessary paraffin.This low-voltage cable fill method also comprises, after this carries out water-cooled step with this cable, cable is dried up with cold wind.This paraffin is that the trade mark is the high melting point paraffin of G22.In this step, in this paraffin, add rosin with the paraffin high temperature melting.In this step, in this paraffin, add 2 percent rosin with the paraffin high temperature melting.
Low-voltage cable fill method among the present invention adopts the method for cable by the paraffin after the high temperature melting, realizes filling, paraffin belongs to neutral products, non-corrosiveness, and normality is that solid does not produce dust, environment without any pollution, is cheaply wanted considerably cheaper than polypropylene, and process very convenient simple, it is extremely low to consume energy, material source is extensive, carries out after cable fills with the method, and cable is filled rounding, national standard can be satisfied, requirement of client can be reached.

Embodiment
For above-mentioned and other purposes, feature and advantage of the present invention can be become apparent, cited below particularlyly go out preferred embodiment, and cooperate appended graphicly, be described in detail below.
As shown in Figure 1, Fig. 1 is the flow chart of low-voltage cable fill method of the present invention.In step 101, in thermostatic bath, paraffin is melted, in paraffin, can add a certain proportion of rosin.In one embodiment, employing be that the trade mark is the high melting point paraffin of G22, the fusing point of this material is 104 ° of C-110 ° C, if add a certain proportion of rosin, in one embodiment, the ratio of rosin is about 2 percent, can guarantee that basically its fusing point is stabilized in about 110 ° of C.Paraffin belongs to neutral products, non-corrosiveness, and normality is that solid does not produce dust, and environment without any pollution, is cheaply wanted considerably cheaper than polypropylene, and processes very convenient simply, and it is extremely low to consume energy, and material source is extensive.It is 70 ° of C that PVC low-voltage cable insulating material allows the maximum operation (service) temperature of conductor, and be filled in the outside of insulation, thermal resistance reckoning according to exhausted insulating material touches the maximum temperature of filling also just about 60 ° of C, therefore paraffin can satisfy the normal service requirement of low-voltage cable fully, also meet GB/T12706.1-2008, the regulation of 7.1.2 " it is also compatible with the insulating material of cable that the material of filler should be fit to the operating temperature of cable ".Flow process enters into step 102.
In step 102, the cable that stranding is good passes through from the paraffin of fusing.Flow process enters into step 103.
In step 103, use the close mould of laying up diameter of a secondary endoporus and cable in the exit of thermostatic bath, by erasing unnecessary paraffin, then filled up by paraffin by the space of cable from this mould for cable.Flow process enters into step 104.
In step 104, cable is cooled off by tank.Flow process enters into step 105.
In step 105, cable is dried up with cold wind.Flow process enters into step 106.
In step 106, cable enters plastic extruding machine and squeezes oversheath, and insulating in construction and use with the protection cable is not damaged.At this moment finished cable will be a rounding very.Flow process finishes.
Fig. 2 is the finished product structure chart through the low-voltage cable after filling among the present invention.One-tenth cable core 21 outsides of this low-voltage cable are filled by paraffin 22, and the oversheath 23 that advanced after plastic extruding machine pushes is smooth smooth.This low-voltage cable of being filled by paraffin can satisfy national standard, can reach client's demand.
