ABB Bailey NKHS03-20 Hydraulic Servo Termination Cable

Product Introduction
The ABB Bailey NKHS03-20 is a specialized hydraulic servo termination cable engineered to ensure seamless, high-integrity signal transmission between control systems and hydraulic servo actuators. Developed under the ABB Bailey family of control and instrumentation components, this cable is a critical accessory in distributed control systems (DCS), particularly in turbine control, hydraulic servo regulation, and motion control systems in heavy industrial applications.

This termination cable is used primarily for connecting electronic modules to servo valves or servo amplifiers in power generation and process automation systems. It ensures minimal signal interference and maintains a robust electrical connection under harsh environmental and mechanical conditions.

Built with industrial-grade insulation and shielding, the NKHS03-20 delivers dependable performance, even in high-vibration and high-temperature zones. It is known for its long service life, superior conductivity, and secure termination characteristics.

Technical Specifications

Product Applications

The ABB NKHS03-20 cable is deployed in mission-critical applications where reliable signal integrity and mechanical durability are non-negotiable. Typical usage scenarios include:

• Hydraulic servo valve feedback and control

• Turbine governor control systems

• Steam and gas turbine servo loop closure

• Distributed Control Systems (DCS) – ABB INFI 90 platform

• Power generation control cabinets

• Valve positioning systems in refineries and chemical plants

• Large industrial automation enclosures requiring secure servo terminations

Its use ensures precise positioning feedback, closed-loop integrity, and a high level of system responsiveness.

Product Advantages

• Engineered for Harsh Environments: Designed for use in high-vibration, temperature-variable areas such as turbine housings and hydraulic control panels.

• Superior Signal Shielding: Dual-layer shielding ensures minimal EMI/RFI interference, enhancing servo control reliability.

• Plug-and-Play Design: Comes pre-terminated for easy integration into ABB systems without requiring field soldering or crimping.

• Long Lifespan: Industrial-grade construction resists oil, moisture, and abrasion, increasing service life.

• Stable Electrical Characteristics: Maintains impedance and capacitance characteristics under dynamic loads and thermal cycling.

• Compatibility Assured: Fully tested and approved for use with ABB INFI 90 and associated hydraulic systems.

• Minimal Installation Time: Reduces labor during commissioning due to standard length and plug-in compatibility.

• Secure Locking Connectors: High-retention force prevents accidental disconnection or vibration-induced loosening.

• Reduced Downtime Risk: Low failure rate supports continuous operation in critical process environments.

• Trusted Brand Backing: Manufactured and quality-controlled under ABB’s rigorous standards for industrial reliability.

Frequently Asked Questions (FAQ)
