Executive Standards: All cables of this series are designed, manufactured, tested and inspected in strict accordance with national standard GB/T9330-2008 and enterprise unified standards QIXCL01.1~6-2015. GB/T9330-2008 is the core national specification for plastic insulated instrument and Control Cables, which systematically stipulates the structural dimensions, material performance, electrical parameters, mechanical strength, anti-interference indicators, aging resistance and finished product testing standards for industrial control cables. Meanwhile, the enterprise standard QIXCL01.1~6-2015 further refines the production process, quality control details and performance grading requirements on the basis of national standards, putting forward higher manufacturing specifications for special anti-interference, flame-retardant, low-temperature resistant and armored control cables. In the whole production process, we implement full-process quality supervision from raw material screening, conductor stranding, insulation extrusion, shielding weaving, armoring protection to finished product aging testing and signal stability detection. Every product batch passes strict sampling inspection and performance verification before delivery, ensuring that each cable has stable signal transmission performance, excellent environmental adaptability and consistent product quality, fully meeting the high-precision and high-reliability operation requirements of industrial automatic control systems.

Product Applications: This series of high-precision instrument and control cables is professionally developed for industrial automated control systems and signal detection scenarios, and is widely applicable to power generation, metallurgy, petrochemical and various industrial and mining enterprises. It is mainly used for signal transmission and circuit connection of distributed control systems (DCS), electronic computer control systems, industrial automatic monitoring systems, as well as precision detection instruments and metering equipment. In modern industrial intelligent production, stable and accurate signal transmission is the core basis for automatic equipment operation. These professional instrument cables adopt multi-layer shielding structure and high-purity conductive materials, which can effectively isolate external electromagnetic interference, avoid signal distortion, data delay and transmission error, and ensure the precise operation of industrial control programs and detection data accuracy.

In addition to high-precision signal transmission scenarios, the product series is also suitable for control loops, monitoring circuits and safety protection lines with AC rated voltage of 450/750V and below. It undertakes important functions such as equipment operation control, real-time operating condition monitoring, fault feedback and safety protection interlock in industrial production lines. Whether it is conventional production equipment linkage control, online real-time data monitoring of industrial instruments, or safety protection circuit signal transmission of key equipment, this series of cables can provide stable and reliable circuit guarantee. With excellent anti-interference performance, stable electrical performance and strong environmental adaptability, it has become the preferred matching cable for intelligent transformation and automatic upgrading of various industrial enterprises.

Service and Laying Characteristics: This series of control cables has distinct temperature resistance grading performance to adapt to different industrial working environments. For conventional ordinary-type cables, the maximum long-term allowable working temperature of the conductor shall not exceed 70℃, which fully meets the stable operation requirements of conventional indoor and conventional industrial environment control circuits. For cross-linked polyethylene insulated models, the optimized formula and cross-linking process greatly improve the high-temperature resistance of the insulation material, and the maximum long-term working temperature can reach 90℃. This high-temperature resistant type can adapt to high-temperature workshops, equipment intensive areas and industrial environments with continuous heat radiation, effectively avoiding insulation aging, performance attenuation and service life shortening caused by long-term high-temperature operation, and improving the overall stability and durability of the control system.

The product has excellent low-temperature resistance performance, with the minimum adaptable ambient temperature reaching -40℃. It can maintain good insulation toughness, structural stability and flexible bending performance in extreme low-temperature environments, without brittle cracking, insulation hardening or signal transmission failure. This feature enables the cable to be normally applied and stably operated in alpine regions, outdoor open-air environments and low-temperature industrial workshops, solving the problem that ordinary control cables are prone to failure in low-temperature environments and greatly expanding the product’s application scope in complex climatic conditions.

In terms of construction and laying specifications, the product has clear and standardized bending radius requirements to ensure the integrity of the cable internal structure and long-term safe operation. For non-armored cables with flexible structure, the minimum allowable bending radius shall be no less than 6 times the cable outer diameter. The flexible design facilitates flexible wiring, corner laying and narrow space construction, which is convenient for on-site construction and installation. For armored cables with metal protective layers, due to the addition of armored mechanical protection structure, the overall rigidity is improved, and the minimum bending radius shall not be less than 12 times the cable outer diameter. Standardized bending construction can effectively prevent structural damage such as armor deformation, insulation extrusion and conductor breakage, ensuring that the electrical performance and anti-interference performance of the cable will not be affected during laying and long-term operation.

In terms of laying environment requirements, the ambient temperature during cable laying construction shall not be lower than 0℃. Construction in ultra-low temperature environment will easily lead to reduced toughness of the cable insulation layer, and bending and traction operations may cause hidden cracks in the insulation and shielding layer, which will affect the long-term safety and stability of the circuit. Therefore, standardized construction temperature specifications ensure the installation quality of the cable and lay a foundation for the long-term stable operation of industrial control systems.
