LION Oil-Resistant Control Cables: TCVN 6610-7 (IEC 60227-7) Compliant Solutions for Industry

In industrial manufacturing environments, workshops, and substations, control cables are constantly exposed to machine oils, solvents, and chemicals, while simultaneously enduring mechanical friction and bending forces. If standard cables are used, the outer sheath will quickly degrade, crack, or become brittle, leading to electrical leakage or signal interference.

The LION Oil-Resistant Control Cable product line (manufactured by DAPHACO) is a specialized solution engineered and rigorously tested in compliance with the TCVN 6610-7 standard (equivalent to IEC 60227-7), perfectly satisfying the most stringent technical requirements of any project.

1. What is the TCVN 6610-7 (IEC 60227-7) Standard?

TCVN 6610-7 is a Vietnamese National Standard that is fully equivalent to the international standard IEC 60227-7. This standard specifies the technical requirements and testing methodologies for polyvinyl chloride (PVC) sheathed cables with rated voltages up to and including 450/750V – specifically focusing on flexible control cables.

When selecting LION control cables certified to TCVN 6610-7 standard, developers and contractors gain complete peace of mind regarding:

• Maximum electrical insulation safety at the specified voltage rating.
• The ability to withstand repetitive bending and flexing tests without any cracking of the cores or the sheath.
• Specialized performance characteristics of the outer sheath when operating in environments contaminated with lubricants and industrial oils.

2. Detailed Structure of LION Oil-Resistant Control Cables

The product is engineered by combining premium materials processed on DAPHACO’s modern technological production lines:

• Conductor (Core): Utilizes 99.99% pure copper. The configuration consists of multiple fine wires stranded together to form a highly flexible Class 5 conductor. This design gives the cable exceptional elasticity, allowing it to withstand the continuous movement of robotic arms or industrial machinery.
• Insulation Layer: Made of tough, flexible PVC to ensure safe electrical insulation between sub-cores. The individual cores are visually identified using standard color-coding or clear sequential numbering (1, 2, 3…), helping technicians wire electrical control panels quickly and accurately.
• Core Covering / Inner Padding: The cores are stranded together concentrically and wrapped securely with a binder/filler layer. This maintains a stable cable structure and keeps it perfectly round, facilitating smooth pulling through technical conduits, cable trays, or ladders.
• Specialized Oil-Resistant Outer Sheath: The core advantage lies in the outermost jacket made from a specially formulated oil-resistant PVC compound. This sheath successfully passes standardized oil immersion testing, meaning it will not swell, crack, or deform even during long-term exposure to machine oil.

3. Standard Operational Technical Specifications

Classification by Environmental Suitability:

• Unshielded Series (Standard Cable): Used for transmitting conventional mechanical control signals.
• Shielded Series (With Anti-Interference Braiding): Enhanced with a woven copper braided shield to protect the signal from distortion and electromagnetic interference (EMI) generated in areas surrounding high-capacity motors.

4. Practical Applications of LION Oil-Resistant Control Cables

Thanks to their oil resistance and international-standard flexibility, this cable line is widely implemented in:

• Control, measurement, and signal connection circuits within automated conveyor systems and assembly production lines.
• Connecting technical control cabinets with machine tools, CNC machines, and lifting equipment in mechanical, processing, and textile factories.
• Elevator systems, escalators, and technical shafts in modern buildings.

5. Why Should Contractors Choose LION Control Cables from DAPHACO?

• Compliant Quality: Products come with full factory certificates and test reports verifying compliance with TCVN 6610-7 (IEC 60227-7) standards, ensuring smooth rigorous acceptance testing in any B2B project.
• High Supply Capacity: DAPHACO’s large-scale manufacturing plant guarantees quick, synchronized fulfillment of multi-specification control cable orders in large volumes for major projects.
