Instrumentation Cables
Yeshwant Wires is a leading instrument cable and instrumentation cable manufacturer in India, offering high-performance cables for precise signal and data transmission in industrial automation systems. Our instrumentation cables are designed to deliver accurate, interference-free communication between field instruments and control panels.
Our instrument cables are manufactured using stranded plain or tinned copper conductors with advanced shielding options including individual and overall aluminum foil/polyester shielding for superior EMI/RFI protection. Available in armoured and unarmoured constructions, these cables ensure long service life, flexibility, and enhanced signal integrity even in harsh industrial environments.
What is an Instrument Cable?
An instrument cable, also known as an instrumentation cable, is a specialized type of electrical cable designed for transmitting low-level signals in industrial environments. These cables are used to connect field instruments such as sensors, transmitters, and control devices to control panels and data acquisition systems. Instrument cables are engineered to provide accurate signal transmission while minimizing interference from electromagnetic sources, making them essential for reliable operation in process automation, oil & gas, petrochemical, power generation, and manufacturing industries.
Description
Yeshwant Wires supplies Instrumentation Cables compliant with UL 13 / UL 2250 Type PLTC/ITC (300V) and UL 1277 Type TC (600V), as well as FOUNDATION™ Fieldbus IEC 61158-2 Type A cables. These cables are available in pair and triad constructions with individual and overall assembly options to meet diverse project requirements.
Our instrumentation cables are widely used in oil & gas plants, petrochemical industries, offshore rigs, power plants, cement factories, refineries, and manufacturing facilities, where reliable low-voltage signal transmission is critical for monitoring, control, and safety systems.
Key Features & Advantages

- Superior EMI Protection: Shielded with aluminium foil or copper braid to prevent interference.
- High Temperature Resistance: Suitable for both indoor and outdoor installations.
- Oil & Chemical Resistant: Outer sheath resists corrosion and harsh industrial conditions.
- Flexible Construction: Simplifies installation through conduits or cable trays.
- Custom Configurations: Single pair, multi-pair, armoured, or unarmoured options available.
- Complies with Global Standards: IS 1554, BS 5308, IEC 189, and EN 50288.
Technical Specifications
| Property | Specification | Significance |
|---|---|---|
| Conductor Material | Annealed Bare / Tinned Copper (Solid or Stranded) | Ensures high conductivity. Tinned copper provides crucial corrosion resistance for damp or chemically active industrial settings. |
| Insulation | PVC / PE / XLPE / FRLS / HR PVC | Offers flexibility to meet thermal and chemical demands. XLPE (Cross-linked) and HR PVC provide higher temperature tolerance; FRLS (Flame Retardant Low Smoke) enhances fire safety. |
| Core Identification | Number Coded or Colour Coded as per Standards | Essential for installation and maintenance to correctly trace and connect circuits (e.g., pairs, triads). |
| Shielding | Aluminium Mylar Tape / Copper Braid / Foil Shield | Critical for protecting sensitive, low-level signals from Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI), ensuring measurement accuracy. |
| Armouring | GI Wire / Steel Tape Armoured (optional) | Provides mechanical protection against crushing, impact, and rodent damage, often required for direct burial or exposed plant routing. |
| Sheath | PVC / FRLS / LSZH (UV & Oil Resistant) | Protects the core bundle from environmental factors. LSZH (Low Smoke Zero Halogen) is key for indoor safety; UV & Oil Resistance is mandatory for chemical and outdoor installations. |
| Voltage Grade | Up to 1100 V | Rated for power-level voltages, allowing safe routing in common trays or conduits with medium-voltage power cables, though the signals transmitted are low voltage. |
| Operating Temperature | -15°C to +85°C | Defines the thermal stability range, indicating suitability for various demanding process environments. |
| Standards | IS 1554 / IS 694 / IS 8130 | Compliance ensures the cable meets international requirements for construction, performance, and testing of industrial control and instrumentation cables. |
Applications
Instrumentation Cables are used in refineries, power plants, automation systems, and control rooms for signal transmission between field devices and control systems. They are suitable for connecting PLCs, DCS panels, transmitters, sensors, and measurement instruments.
Manufacturing & Quality Assurance
At Yeshwant Wires, every instrumentation cable is produced using advanced extrusion, twisting, shielding, and armouring processes for precision and reliability. Cables undergo stringent testing for continuity, insulation resistance, capacitance, attenuation, and flame retardancy under ISO certified quality systems.
