When selecting a control cable, a cable produced by a regular manufacturer must be selected to ensure normal operation during use. After the control cable is put into use, there will be electrical interference between different cores of the same cable and between cables placed parallel to each other. So what do we need to know to deal with? The following Tianxing cable editor will explain to you how to choose control cables and precautions for use.



1, control cable overview

Cables connected from the control center to various systems to transmit signals or control operational functions are collectively referred to as control cables. The early functions of the control cable are relatively simple, including: indicator light display, appearance indication, operation of relays and switchgear, alarm interlocking system, etc. In recent years, due to the wide application of weak current and computer network, the selection and application of new control cables have put forward higher functions and higher requirements.

2, the main series of control cables, the main products of control cables today are: polyvinyl chloride insulated control cables, natural styrene butadiene rubber insulated control cables and polyethylene insulated control cables. There are also products with cross-linked polyethylene insulation and ethylene propylene rubber insulation. At present, China can also produce 600/1000V plastic insulated control cables. The rubber insulated control cable has an additional voltage of 300/500V. The core of the control cable is copper, the nominal cross section is 2.5mm2 or less, and the core wires are 2 to 61 cores. 4 ~ 6mm2, 2 ~ 14 cores; 10mm2, 2 to 10 core control cable operating temperature: rubber insulation 65°C, PVC insulation 70°C and 105°C. The control cables used in computer systems are usually insulated products made of polyvinyl chloride, polyethylene, crosslinked polyethylene and fluoroplastics.

3, to ensure the normal operation of the control cable and avoid interference

In order to ensure that the control cable reduces the damage range in case of insulation breakdown, mechanical damage or fire, dual maintenance Separate control cables should be used for two systems that need to improve reliability, such as: current, voltage, DC power supply and trip control loop.
