In industries where safety, control, and efficiency are non-negotiable, Copper Instrumentation Cables form the backbone of reliable data transmission. These cables are essential for carrying low-voltage signals used to monitor and control critical processes. Capital Cables is a Leading Distributor of Polycab Wires & Cables, providing high-quality instrumentation cables that meet the demanding requirements of modern process-driven industries.
What Are Instrumentation Cables?
Instrumentation cables are low-voltage copper cables designed specifically for transmitting data and analog signals from instruments and sensors to control rooms in industrial environments. These cables ensure precise monitoring and command execution by enabling real-time communication between the field devices and centralized control systems.
The core function of an instrumentation cable is to preserve the integrity of sensitive signals while protecting them from noise, electromagnetic interference (EMI), and harsh operating conditions. This is made possible through superior shielding, insulation, and construction methods.
Where Are Instrumentation Cables Used?
Instrumentation cables are vital in:
- Oil & Gas Refineries
- Fertilizer Plants
- Cement Manufacturing Units
- Steel & Power Plants
- Chemical Processing Industries
- Pharmaceutical and Food Industries
- Water Treatment Facilities
In these continuous process plants, variables such as temperature, pressure, level, and flow are constantly monitored. These parameters are converted into electrical signals that are transmitted to a control room. Polycab instrumentation cables ensure these signals reach their destination noise-free and accurately, enabling corrective actions based on real-time data.
Key Features & Benefits of Polycab Instrumentation Cables
Polycab’s advanced instrumentation cable technology is trusted across industries for its consistent performance. Distributed by Capital Cables, these cables are engineered to deliver several benefits:
- Noise-Free Signal Transmission
High shielding efficiency minimizes interference from external electrical sources, ensuring precise data flow. - Flame Retardant
Cables are built with flame-resistant materials to prevent flame propagation and enhance safety. - Low Smoke Emission
In case of fire, low smoke output aids visibility and minimizes toxic exposure during evacuation. - Long Service Life
Designed with superior materials to perform reliably even in challenging environments, ensuring long-term operational continuity. - High Shielding Efficiency
Options for individual and collective screening using Al-mylar tape and copper drain wire or ATC braiding offer enhanced protection against EMI/RFI.
Polycab instrumentation cables combine performance and protection, making them ideal for critical infrastructure and process automation.
Technical Specifications
Polycab’s copper instrumentation cables are manufactured with attention to detail, conforming to the highest quality standards. Below is a breakdown of their construction and technical attributes:
Voltage Rating

The diverse configuration options allow for optimal customization based on project complexity and space availability.
Why Shielding Matters in Instrumentation Cables
One of the most critical requirements in instrumentation cables is signal integrity. Industrial environments are full of electrically noisy equipment such as motors, drives, and high-voltage lines. Without adequate shielding, data signals may become distorted or unreadable.
Polycab instrumentation cables solve this challenge using:
- Individually Shielded Pairs/Triads to eliminate crosstalk between adjacent signals.
- Overall Screening to protect against external EMI/RFI interference.
This results in clean, uninterrupted signal transmission, which is vital for precise instrumentation and control.
