Abstract
The utility model provides a rubber sleeve cable continuous cure pipeline with waterproof pull head, has rubber sleeve cable continuous cure pipeline, its characterized in that: still have waterproof pull head in the curing tube, waterproof pull head is a cylindrical iron bar, and each division of iron bar both ends has an oval -shaped through -hole, and the every interval 20mm of iron bar is equipped with an annular recess. Get up two cable junction through waterproof pull head, oval through -hole is connected with cable conductor, and during operation in the curing tube, recess through waterproof pull head can effectively prevent cable sheathing and the cable core to intake, adopt the utility model discloses the rubber sleeve cable of production drops 0 to by the rate of intaking 50% originally, has improved production efficiency greatly, has reduced manufacturing cost.
Description
Technical field
The present invention relates to field of cables, specifically the waterproof pull head that uses in continuous vulcanization pipeline of a kind of Plastic-sheathed Cable.
Background technology
Plastic-sheathed Cable sulfidation is under high steam and high hydraulic pressure, complete the crosslinked transformation of rubber chemistry, makes material be transformed into the overall process of vulcanized rubber by raw rubber.General continuous vulcanization production line pipeline Design of length is within the scope of 120 ~ 180 meters, and the good and bad pressure size depending on steam and cooling water in curing tube of sulfidation, also depends on line speed and cross-section of cable size simultaneously.Original Plastic-sheathed Cable does a method: first conductor in cable core and pull rope are twisted and be connected together, then with electrician's black adhesive plaster, the joint layer upon layer of naked leakage is wound around consolidation, but under 200 DEG C of 1.5MPa high-pressure water vapor pressure, any material is all difficult to keep out, there is water inlet phenomenon in the cable of 50%, by the impact of high-pressure water vapor, general floodable length is up to about 60 meters, after water enters into cable conductor, corrosion blackening effect is produced rapidly to conductor, insulation resistance is made significantly to decline 50%, although cable manufactures complete, but need to take water extraction way to carry out draining, extend cable Production Time, time-consuming.
Summary of the invention
For solving the problem, the invention provides a kind of Plastic-sheathed Cable continuous vulcanization pipeline with waterproof pull head, there is Plastic-sheathed Cable continuous vulcanization pipeline, it is characterized in that: with a waterproof pull head in described curing tube, described waterproof pull head is a cylindrical iron staff, iron staff two ends respectively have an oval through hole, and iron staff is provided with an annular groove at interval of 20mm.Oval through hole is connected with cable conductor, two sections of cables couple together by waterproof pull head, the water inlet of cable cross section is stoped by the groove in waterproof pull head, in the course of the work, Plastic-sheathed Cable realizes resistance effect between sheath and cable core by waterproof pull head extrusion pressure by flowing rubber injection groove to Plastic-sheathed Cable continuous vulcanization pipeline.According to the difference of production mould, waterproof pull head can be different size.In Plastic-sheathed Cable continuous vulcanization pipeline, multiple waterproof pull head can be set.Adopt the Plastic-sheathed Cable that the present invention produces, water inlet rate is 0, substantially increases production efficiency, reduces production cost.
Accompanying drawing explanation
Fig. 1 is the structure chart of waterproof pull head.
Embodiment
Embodiment 1:
As shown in Figure 1, a kind of waterproof pull head in Plastic-sheathed Cable continuous vulcanization pipeline, waterproof pull head is the cylindrical iron staff that a length is 305mm, diameter is 10mm, waterproof pull head rear and front end respectively has an ellipse hole, the length of described through hole is 15mm, width is 5mm, and cylindrical iron staff is provided with an annular groove every 20mm, and recess width is 5mm.Waterproof pull head is put into curing tube, waterproof pull head rear and front end is respectively connected with a conductor, Plastic-sheathed Cable and waterproof pull head in curing tube in the course of work, by waterproof pull head with groove, prevent sheath and cable core from intaking, described groove has resistance effect.
The cable performance indexes contrast adopting the present invention to produce is as follows:
| Experimental project | Standard-required | Before improvement | After improvement |
| Insulation resistance (+20 DEG C) M Ω km | ≥425 | 200 | 1000 |
The present invention is in Plastic-sheathed Cable production process, and the water inlet rate by original 50% is transformed into 0 water inlet rate, substantially increases production efficiency.
Claims (1)
1. the Plastic-sheathed Cable continuous vulcanization pipeline with waterproof pull head, there is Plastic-sheathed Cable continuous vulcanization pipeline, it is characterized in that: also with waterproof pull head in described curing tube, described waterproof pull head is a cylindrical iron staff, iron staff two ends respectively have an oval through hole, and iron staff is provided with an annular groove at interval of 20mm.
