KVVR PVC Insulated and Sheathed Control Flexible Cable
Model Number
Copper Core Polyvinyl Chloride Insulated Polyvinyl Chloride Sheathed Flexible Control Cable
Number of Cores
Multi-core
Structure Description
KVVR is a type of flexible control cable with copper core polyvinyl chloride insulated and polyvinyl chloride sheathed. It has a structure that takes into account both flexibility and anti-interference performance. The conductor is made of multiple strands of copper wire, which enhances flexibility. Each conductor is uniformly wrapped with polyvinyl chloride (PVC) insulation, forming an independent insulated core. The insulated cores are twisted together, and some specifications include an additional copper wire braid for shielding to reduce electromagnetic interference. The outer layer is wrapped with PVC sheath, providing oil resistance, weather resistance, and flame retardancy.
Application Scope
KVVR (Copper Core Polyvinyl Chloride Insulated Polyvinyl Chloride Sheathed Flexible Control Cable) is a type of multi-core flexible cable, mainly used for frequent movement or bending of equipment, suitable for industrial automation, building electrical, transportation facilities, etc. It has good flexibility and environmental adaptability, widely used in control cabinets, instruments, equipment, buildings, lighting, machinery, robots, and communication systems. Especially suitable for environments with frequent mechanical stress or low-voltage power supply, it has good oil resistance, weather resistance, and flame retardancy, further expanding its application in mines, metallurgy, and other complex industrial environments.
Brief Introduction KVVR (Copper Core Polyvinyl Chloride Insulated Polyvinyl Chloride Sheathed Flexible Control Cable) is a multi-core flexible control cable. Its conductor is made of multiple strands of copper wire, with an outer layer of polyvinyl chloride (PVC) insulation and a double protective layer. It has good flexibility, oil resistance, corrosion resistance, and wear resistance. It is suitable for frequent movement or complex environments, widely used in control cabinets, instruments, equipment, buildings, and other industrial automation, machinery, transportation, construction, and electrical fields, especially suitable for environments with frequent mechanical stress.
Advantages
1. Flexible and durable: Multi-stranded copper conductor and flexible structure design, suitable for frequent movement or small space wiring, strong mechanical strength.
2. Environmental resistance: PVC insulation and sheath provide double protection, oil resistance, acid and alkali resistance, moisture resistance, and wear resistance, suitable for complex industrial environments (such as chemical plants, mines).
3. Easy installation: Flexible cable, easy to bend and fold, reducing construction difficulty and time cost.
4. Safe and reliable: Insulation stability, strong anti-interference ability, ensuring the stability of control signals and low-voltage power supply transmission.
5. Economical and practical: Good performance and cost-effective, widely used in automation equipment, transportation, construction, and electrical fields, with excellent cost-performance ratio.
Usage Scope
KVVR (Copper Core Polyvinyl Chloride Insulated Polyvinyl Chloride Sheathed Flexible Control Cable) has good flexibility, oil resistance, corrosion resistance, and wear resistance, widely used in environments requiring frequent movement or complex wiring, such as industrial automation, machinery, equipment, robots, communication systems, building control, and lighting systems. Its environmental adaptability makes it suitable for chemical plants, mines, and other complex environments, especially suitable for low-voltage power supply, control signal transmission, and instrument connection in environments with frequent mechanical stress, making it an ideal choice for complex industrial and building electrical fields.
Specification
KVVR cable (copper core polyvinyl chloride insulated polyvinyl chloride sheathed control cable) commonly includes specifications ranging from 0.5mm² to 6mm² (such as 0.5, 0.75, 1.0, 1.5, 2.5, 4, 6mm²), with voltage ratings of 450/750V. The insulation is made of PVC, available in various colors (red, yellow, blue, green, yellow-green, etc.), compliant with GB/T 5023 or IEC 60227 standards, suitable for various electrical installations.
Cost and Materials
The cost of KVVR cable is mainly composed of copper conductor, polyvinyl chloride (PVC) insulation and sheath materials. Its conductor is made of multiple strands of fine copper wire (Class 5), and the price fluctuation of copper material directly affects the cost; the insulation layer and sheath are made of oil-resistant and corrosion-resistant PVC material, and high-performance additives (such as flame retardants and plasticizers) will increase the material cost. In addition, the multi-core structure (2~61 cores) and complex processes (such as twisted cables and outer wrapped reinforcement layers) increase the difficulty of production and labor costs. Although the initial cost is higher than that of ordinary cables, its durability, resistance to mechanical stress and environmental adaptability reduce long-term maintenance costs, and the cost performance is outstanding. Special requirements (such as shielding layer, customized length or high-specification certification) will further affect the total cost.
History
The history of KVVR (copper core polyvinyl chloride insulated polyvinyl chloride sheathed control cable) dates back to the mid-20th century with the widespread application of PVC materials in cable manufacturing. Following World War II, the rapid industrialization led to increased demand for oil-resistant, weather-resistant cables, making PVC an ideal material due to its low cost, ease of processing, and excellent properties, becoming a mainstream insulation material. Since the 1980s, with the establishment of the cable industry in China and the introduction of international standards, the manufacturing of KVVR cables has gradually evolved. The 1990s saw the implementation of GB/T 9330 national standards, further standardizing design and manufacturing processes. Material and process optimizations (such as improved oil resistance, weather resistance) have expanded applications in transportation, smart buildings, and other high-demand scenarios, becoming an indispensable cable type in industrial control systems.
Process
The manufacturing process of KVVR cable covers key links such as conductor twisting, insulation extrusion, cabling wrapping and sheath extrusion: First, multiple strands of fine copper wire (Class 5) are twisted in layers according to a specific pitch to ensure the softness and balanced conductivity of the conductor; then the PVC insulation layer is evenly coated through a high-temperature extruder, and the wire cores are color-coded for easy identification; after the multi-core wire harness is twisted by a cabling machine, a polyester tape or non-woven fabric is wrapped around it to enhance the structural stability; finally, the whole is extruded with a weather-resistant PVC sheath, and the wear and oil resistance is improved through a precise temperature control molding process. During the production process, the twisting density, insulation thickness and sheath adhesion are strictly controlled, and the cable is subjected to conduction tests, voltage resistance tests and bending life tests to ensure that the cable meets standards such as GB/T 9330 and meets the mechanical strength and signal transmission reliability requirements in complex environments.
