Description
Technical field
Special equipment or method the present invention relates to manufacture conductor or cables manufacturing are specifically a kind of heating cables
Extrusion equipment.
Background technique
The main production process of power cable (power supply line series) has following steps:
The common copper of wire and cable, aluminium bar material pass through one or the mould of several drawing die using wire drawing machine at normal temperature
Hole reduces its section, length increases, intensity improves.Wire drawing is the first working procedure of each wire and cable company, the main work of wire drawing
Skill parameter is with mould technology.
Copper, aluminium monofilament are improved the toughness of monofilament in a manner of recrystallization, reduce monofilament at a temperature of being heated to certain
Intensity, to meet requirement of the wire and cable to conductor wire core.Annealing operation key is to prevent the oxidation of copper wire.
In order to improve the pliability of wire and cable, in order to laying installation, conductor wire core takes multifilament to be twisted.
From the twisted formal of conductor wire core, it is twisted and irregular twisted that rule can be divided into.Irregular be twisted is divided into bundle strand again, answers with one heart
It twists, is special twisted etc..
In order to reduce the area occupied of conducting wire, reduce the geometric dimension of cable, is used while stranded conductor and press shape
Formula, making typical circular variation is semicircle, sector, shoe and the circle pressed.Such conductor is mainly used on power cable.
The single line for constituting twisted wire is to be stranded in around twisted wire center in layer orderlyly, and adjacent twisted layer is twisted to phase
Instead.Concentric lay is also known as regular twisted.
