LIYY Unscreened Signal and Control Cable for Flexible Low-Voltage Wiring

ETK Kablo’s LIYY cable is a flexible, unscreened signal and control cable engineered for indoor low-voltage communication and automation systems. Designed for environments with minimal electromagnetic interference (EMI), it delivers stable and efficient data or control signal transmission in compact wiring applications.

Reliable Performance for Control and Data Applications

The cable features fine-stranded bare copper conductors with PVC insulation and a robust PVC outer sheath. This structure provides mechanical durability, easy handling, and smooth installation in confined routing spaces such as control cabinets, panels, and instrumentation racks. The unscreened design makes it ideal for systems that do not require EMI shielding, offering a cost-effective and lightweight cabling option.

Versatile Use in Industrial and Building Automation

ETK Kablo’s LIYY cable is commonly used in building management systems (BMS), HVAC control units, electronic devices, measurement circuits, and process control wiring. Its flexibility supports fast installation and reliable signal routing, while DIN color-coded cores simplify identification and maintenance.

Safe and Efficient Low-Voltage Operation

Designed for fixed indoor installations in dry or lightly humid conditions, the LIYY cable ensures accurate data flow and control signal integrity across low-voltage circuits. The tough PVC jacket offers abrasion resistance and mechanical protection during installation and service life.

Compliance and Quality Assurance

This cable complies with IEC and VDE standards for signal and control cabling, ensuring consistent performance, quality, and long-term reliability within structured cabling systems.

Why Choose ETK Kablo’s LIYY Cable?

Choose ETK Kablo’s LIYY — the versatile unscreened control cable designed for dependable performance, flexibility, and precision in automation, panel wiring, and signal transmission where EMI shielding is unnecessary.

Frequently Asked Questions about LIYY Signal and Control Cables

What is LIYY cable?

LIYY cable is a flexible, unscreened signal and control cable designed for use in low-voltage control circuits, electronic equipment, and instrumentation systems. It features fine-stranded copper conductors with PVC insulation and sheath, making it suitable for indoor installations where electromagnetic interference (EMI) protection is not required.

What is a signal cable?

A signal cable is used to transmit low-voltage electrical signals between devices, sensors, or control units. These cables ensure accurate and noise-free data transfer in automation, measurement, and monitoring systems. Depending on EMI exposure, signal cables can be screened (e.g., LIYCY, LIHCH) or unscreened (e.g., LIYY).

What is the difference between signal cable and control cable?

While both cable types transmit electrical information, a signal cable typically carries data or measurement signals between sensors and control equipment, whereas a control cable transmits commands or power signals between control panels and actuators. ETK Kablo’s LIYY cable serves as both — providing reliable signal and control performance in automation and instrumentation environments.
