2YSLCYK-J 0.6/1 kV Single-PE VFD Motor Cable

2YSLCYK-J cable for VFD-to-motor connections

2YSLCYK-J is a 0.6/1 kV screened motor power cable for connections between a variable frequency drive and a three-phase motor. This page covers the black PVC, four-core construction with three phase conductors and one full-size protective-earth conductor. It gives buyers a clear starting point for replacing a marked cable or specifying a new industrial drive route.

PE insulation supports a low-capacitance design, while the combined foil and copper-braid screen helps manage electromagnetic interference along the power connection. The choice still depends on the complete drive system: cable length, motor loading, routing, bonding and the converter manufacturer’s installation requirements all matter. A matching model name alone does not establish a drop-in replacement.

• Choose this arrangement when the equipment design calls for a conventional four-core power connection with a single protective-earth core.
• Match the route to fixed installation or occasional free movement, with space for the bend radius of the selected diameter.
• Compare dimensions before selecting glands, terminals and cable supports; the size table provides reference values for that review.
• State the duty if the existing installation involves repeated guided motion or a different earth arrangement, so the replacement construction can be assessed.

Construction

The selected 2YSLCYK-J design combines four PE-insulated copper cores with two overall EMC screens beneath a black PVC sheath.

Screening and mechanical protection

The foil and copper braid form the electrical screen. The reinforced PVC description applies to the outer sheath; the construction has no separate armour layer. Maintain screen continuity through suitable terminations and select mechanical protection to suit the cable route.

Applications

Use this four-core VFD motor cable where the drive connection requires a single protective-earth conductor, medium mechanical duty and a screened power route.

• Machine-tool motor supplies and stationary manufacturing equipment.
• Conveyors, handling equipment and production-line drives.
• Fixed wiring and occasional free movement in dry, damp or wet areas and outdoors.

Routing and EMC termination

Allow free movement without tensile loading or forced guidance. Select a different documented construction when the route requires continuous drag-chain cycling, repeated torsion or unsupported suspended loads. Preserve the required bend radius at glands, supports and cabinet entries.

Follow the converter and motor instructions for screen bonding. A broad circumferential braid connection at the specified ends preserves the intended screening arrangement; a screen is not an additional insulated earth core. The cable shielding guide explains how braid construction affects screening and termination choices.

Choosing between related motor cables

This page specifies PE insulation and four equal-size cores with one protective-earth core. The related 2XSLCYK-J uses XLPE insulation, while the related 2YSLCYK-JB uses a 3+3 split-earth layout. The existing 2YSLCY-JB range has a transparent PVC sheath; compare the complete construction before substituting.

Specifications

Minimum bending radius

D is the finished cable outside diameter. Apply the radius for the actual supplied diameter and installation mode.

Four-core size and weight data

These are approximate reference-design values for the black-sheath version. Confirm finished diameter and weight for the selected order before fixing gland and support sizes. G includes one green/yellow protective-earth core; all four cores have the stated cross-section.

Current values are reference figures at 30 °C air temperature, not universal installation ratings. Determine permissible current for the actual route, grouping, ambient temperature and loaded conductors. Provide motor current, route length and installation method when selecting the cross-section.

Standards

The following construction and test references apply to the specified 2YSLCYK-J reference design.

IEC 60228 defines conductor classes and resistance requirements. Include the applicable inspection and test-document requirements with the selected cable configuration.
