According to the mode of winch, winch can be divided into single winch, high speed winder, twisting machine, cage winder, frame winder, tubular winch and disc winder. Analysis on the classification and application of winch by Dongguan cable manufacturer. There are two kinds of single winch, vertical single winch and cantilever single winch. It is mainly used in HDMI,DP,USB,CAT-7 high frequency wire, electronic cable, data cable, core wire pair and multiple strands. The winch is mainly used in the winch of high frequency data cable. High speed winch can be divided into automatic tension high speed winder and manual tension high speed winder. Its Mainly used in computer wire arrangement, headphone wire, electronic wire, telephone wire, network wire, PVC wire copper wire hanging. The torque remover is used in high frequency digital telephone cable, so that the position of insulated core wire is staggered and balanced when twisted, and the torsional force is uneven when twisted, so that the high speed twisted pair can still be of uniform quality and accurate pitch, and the torsional effect is good and the performance is excellent.
