Security monitoring lines and weak lines can be arranged at the same time
From the name can be seen in the three main purposes of the cable, the power cable is to provide power for the operation of the device, characterized by high voltage, current is large, so the cable voltage and other aspects of higher requirements; control and communication The cable carries the current and voltage is relatively low, but because of its signal is the amount of communication and analog or even high-frequency signals (such as television video signal), easy to receive electromagnetic interference and its signal distortion or false signal , Which control the accuracy, accuracy and image, sound and so have a great impact, and even cause serious production accidents, so this type of cable on the signal shielding requirements are high, mainly to ensure that its bearer signal from or Reduce external interference.

Irradiation processing of wire and cable generally refers to the formation of cross-linked covalent bonds between the insulating layer of the wire and cable and the polymer material of the sheath layer under the irradiation of the high-energy electron beam to form a mesh or body structure. Irradiation cross-linking. After the radiation cross-linked modified wire and cable its strength, elasticity, hardness have been improved, solvent resistance, resistance to environmental stress cracking has also greatly improved, the most important is the heat resistance and short circuit temperature has been obvious improve.
