Product feature and purpose:

Control  Cable

Control cable is a kind of cable specially used for industrial and mining enterprises, energy and transportation departments and other occasions to protect the circuit, the main material is polyvinyl chloride. The design of the control cable is mainly to meet the needs of the rated AC voltage below 450/750 volts to control and protect the line. Its main features include: insulation and sheathing material ‌ : polyvinyl chloride insulation and polyvinyl chloride sheathing are usually used. This combination of materials gives the cable good electrical properties and mechanical protection. Application field :Widely used in industrial and mining enterprises, energy and transportation departments need to control and protect the line occasions. cable structure: The internal structure of the control cable is relatively complex, including multiple layers of protection and shielding to ensure the stability and safety of signal transmission. For example, some control cables have copper tape shielding to ensure that the transmitted signal is stable, while steel tape armor is used to protect the cable from mechanical damage. model identifier : The model identifier of the control cable contains key information about the cable, such as the number of cores and cross-sectional area of cores. For example, the "7 x 2.5" in the model "ZR-KVVP2-22" indicates that the cable has seven cores, each with a cross-sectional area of 2.5 square millimeters. Material used : The core of the control cable is usually copper conductor, because copper has good electrical conductivity and corrosion resistance. In addition, according to different application requirements, the control cable can also use aluminum conductors or cross-linked polyethylene insulation, polyethylene insulation and other materials. Rated voltage and temperature rating : The rated voltage of the control cable is generally 450/750V, while the operating temperature varies according to the insulation material. For example, the operating temperature of the polyvinyl chloride insulated control cable can reach 70℃. In order to ensure the normal operation of the control cable, reduce electrical interference and ensure safety, relevant standards and specifications (such as GB 50217-2018 "Code for the Design of Power Engineering cables") specify the use and installation requirements of the cable, for example, for systems that need to enhance reliability, separate control cables should be used to reduce the spread range. In summary, a control cable is an important type of cable specifically designed to control and protect circuits, whose characteristics and uses ensure the safe and reliable operation of critical systems in industry and infrastructure
Operative standard:

GB/T 12706,IEC 60502 and relevant domestic and international standard.For example,BS,VDE,JIS,AEIC,and GB JL LHA NRLH JK series so on.

Operational performance:
The maximum allowable operating temperature of the cable conductor:90 C in normal condition and 250 C in case of short circuit (maximum duration of short circuit is 5s).
