Introduction
Instrumentation cables play a critical role in power generation, distribution, and numerous industrial sectors such as chemical, fertilizer, cement, and steel manufacturing. These cables are designed to ensure precise measurement, supervision, and control of various processes by transmitting low-level electrical signals between sensors and control systems. As industries increasingly adopt microprocessor-based and computerized instrumentation, the demand for high-quality instrumentation cables with stringent electrical parameters has surged.
These low-level electrical signals are prone to external noise pickup during transmission, which necessitates carefully designed cables to ensure noise-free signal transmission and high shielding efficiency. Capital Cables specializes in manufacturing and supplying high-performance instrumentation cables that adhere to Indian and international standards, offering superior reliability, flame retardancy, and low smoke emissions.
Applications of Instrumentation Cables
Instrumentation cables are utilized in various industrial processes where communication between instruments is vital for control and automation. They are used in:
- Power plants: For monitoring and controlling temperature, pressure, and flow rates.
- Refineries and petrochemical industries: To ensure safe and efficient operations by transmitting accurate data between field instruments and control rooms.
- Steel and cement manufacturing: Where accurate instrumentation is required to control production processes.
- Fertilizer industries: Where chemical reactions need to be closely monitored.
- General industrial automation: Instrumentation cables are also used in food processing, pharmaceuticals, and other manufacturing units for precise monitoring and control.
These cables can be screened, armored, laid up in pairs, triads, and quads, and can be insulated in various materials, including PVC, PE, XLPE, and HEPR, with sheathing options such as PUR, LSF, PVC, and PE.
Key Features of Instrumentation Cables
High-quality instrumentation cables offer several essential features that ensure uninterrupted industrial operations:
Low Smoke Emission
Instrumentation cables are designed with low smoke and halogen-free insulation, ensuring safety in enclosed industrial environments by minimizing toxic emissions in case of fire.
Long Life & Durability
Manufactured with high-quality materials, Capital Cables’ instrumentation cables are resistant to wear and tear, extreme temperatures, and harsh industrial conditions, ensuring long service life.
Flame Retardant & Fire Resistant
Noise-Free Signal Transmission
Shielded and screened instrumentation cables reduce electromagnetic interference (EMI) and external noise pickup, delivering clean and accurate signals even in the most demanding industrial environments.
High Shielding Efficiency
Types of Instrumentation Cables
Shielded & Screened Instrumentation Cables
Shielded cables are wrapped with conductive layers to prevent interference and ensure noise-free signal transmission. These are widely used in areas prone to electrical noise and EMI interference.
Armored Instrumentation Cables
These cables are reinforced with GI (Galvanized Iron) armor wire for extra mechanical protection, making them suitable for harsh industrial environments.
Paired, Triad & Quad Cables
- Paired cables: Used in basic industrial applications.
- Triad cables: Ideal for three-phase signal transmission.
- Quad cables: Offer high signal integrity and redundancy.
