LIYY Cable for Unscreened Signal and Control Wiring

LIYY cable is a flexible multicore signal and control cable with PVC insulation and a PVC outer sheath. ETK Kablo manufactures this unscreened design with Class 5 stranded copper conductors arranged in layers for circuits that do not require a metallic electromagnetic screen.

Part of our unscreened PVC signal control cable range, LIYY provides connections for instrumentation, industrial electronics and indoor communication equipment.

Applications and Cable Selection

Typical uses include measurement circuits, control panels, electronic equipment and indoor sound systems. The stranded conductors help installers route the cable through equipment enclosures and fixed wiring pathways.

Select the conductor count and cross-section according to the circuit load, voltage drop and equipment requirements. Also check the electrical environment: LIYY has no foil or copper braid screen, so routes near strong interference sources may require a screened alternative.

Selected LIYY Cable Sizes

The table below lists selected configurations from the published LIYY range. In a size such as LIYY 4×0.75 mm², the first number indicates four conductors, each with a cross-section of 0.75 mm².

LIYY 4×2.50 mm²42.50 mm²

For the full range, part numbers, dimensions, weights and packing lengths, see the Types section on this page. Available conductor counts depend on the selected cross-section.

Core Identification and LIYY OZ Options

The standard construction references DIN 47100 core identification. The product datasheet also lists JZ, OZ, JB and OB identification options according to customer requirements. If your specification calls for LIYY OZ, include that designation together with the conductor count and cross-section in your enquiry.

Frequently Asked Questions

What is the difference between LIYY and LIYY-TP?

Standard LIYY uses individual insulated conductors stranded in layers. LIYY-TP groups conductors into twisted pairs, while TT denotes twisted triads. For grouped circuits, see the separate LIYY-TP/TT signal control cable. These constructions remain unscreened.

What is the difference between LIYY and LIYCY?

LIYY is unscreened, whereas LIYCY cable includes an overall tinned copper braid screen. Choose the screening arrangement according to the circuit and installation environment.

Is LIYY halogen-free or fire resistant?

LIYY uses PVC insulation and sheathing, so it is not a halogen-free cable. Its documentation lists IEC 60332-1-2 flame-retardancy testing, which does not establish circuit integrity during fire. Projects requiring halogen-free materials should select a suitable product from our LSZH signal control cable range.

Does flexible construction mean LIYY is suitable for drag chains?

No. Class 5 conductors provide flexibility for handling and routing, but do not by themselves establish suitability for continuous flexing. Applications involving repeated movement require a cable with documented performance for that duty.

Request a LIYY Cable Quotation

Contact ETK Kablo with the required conductor count, cross-section, core identification, quantity and packing lengths. Include the circuit voltage and installation conditions so we can confirm the appropriate LIYY configuration.
