Row annealing, the temperature of annealing are 550 DEG C, then pass through water cooling；
(3) it is twisted: several one metal wires being subjected to multiple twist with one heart and obtain cable core；
(4) it coats: with extruding machine in cable core outer surface extruded insulation layer；
(5) stranding: the conductor strand after will be insulating exruded is circle.
Preferably, the step (4) the specific steps are by the cable core in step (3) add insulating layer, blank
It is fitted into before carrying out cold-extruded in the barrel squeezed, heating appropriate first is answered to mold and cylinder barrel, mold temperature control is at 60 DEG C, cylinder
35 DEG C of temperature of cylinder, the electric wire after cold-extruded should be dried first, then the temperature of drying is sintered electric wire after drying, at 200 DEG C for thin
Wall insulation, sintering temperature general control control at 380 DEG C wall thickness insulation temperature, are cooled to room temperature at 400 DEG C；
Preferably, the insulating layer includes: 40-75 parts of dimethyl silicone rubber, Lauxite 22-35 by weight
Part, 10-20 parts of fire retardant, 5-10 parts of antioxidant, 3-8 parts of plasticizer, 1-3 parts of antistatic agent and 1-5 parts of foaming agent.
It compared with prior art, is all mechanical as slidingtype is continuously drawn using modernization in art production process of the invention
Silk machine, continuous annealer etc., production efficiency and product quality not only can be improved in this, reduce labor intensity and rejection rate but also
Also reduce the production cost of enterprise.Insulating layer of the invention is formed by non-crosslinked resin composition, which has excellent
Flame retardant property, excellent battery fluid are resistant to performance, excellent wear-resisting property.
Specific embodiment
