2XSL(st)CH Cable

What is 2XSL(st)CH LSZH Cable?

The 2XSL(st)CH LSZH cable is a low-voltage, unarmored and double-screened flexible VFD motor supply cable featuring Class 5 flexible plain copper conductors, XLPE insulation, a PET separator, a dual-layer Al/PET and TCWB screen, and a black LSZH outer sheath complying with DIN EN 50267-2, IEC 60502-1, and IEC/EN 60332-1-2 standards. It is designed for fixed wiring, cable trays, trunking, and flexible connection up to 0.6/1kV between frequency converters and inverter-driven motors where EMC protection and low smoke zero halogen performance are required.

Engineered to mitigate high-frequency electromagnetic noise and eliminate hazardous toxic gas release in enclosed industrial spaces, the cable pairs low-dielectric XLPE core insulation with a comprehensive 100% foil wrap and heavy-duty tinned copper braid. This dual-layer shielding topology confines high-frequency harmonics generated by variable frequency drives while the halogen-free outer compound ensures clear evacuation corridors and zero acid gas corrosion in mission-critical processing plants and public commercial facilities.

2XSL(st)CH LSZH Cable Construction

• Conductor: Class 5 flexible stranded plain bare copper conductors per IEC/EN 60228 delivering superior conductivity and dynamic flex endurance.
• Insulation: Cross-linked Polyethylene (XLPE) compound offering low mutual capacitance and high thermal overload capacity up to +80°C.
• Bedding / Separator: Polyester Tape (PET) separator applied over the assembled cores for structural stability and smooth core movement.
• Screen / Armour: Dual-layer screening system combining an Aluminium Polyester Tape (Al/PET) and an overall Tinned Copper Wire Braid (TCWB) for complete 360-degree EMC suppression.
• Outer Sheath: Low Smoke Zero Halogen (LSZH) thermoplastic compound, flame retardant per DIN/BS EN/IEC 60332-1-2 and halogen-free per IEC/EN 60754-1/2.
• Core Identification: 4 full cores (Green/Yellow, Brown, Black, Grey) or 3 power cores + 3 split earth conductors.
• Sheath Colour: Black.

Applications

2XSL(st)CH LSZH cables are specifically engineered for variable frequency drive (VFD) motor connections, converter feeds, and high-power industrial equipment across facilities demanding stringent fire safety and electromagnetic interference (EMI) suppression. Their UV-resistant LSZH formulation allows installation on cable trays, in ducts, trunking, and outdoor exposed setups without direct burial.

Typical installation environments include:

• Variable Speed Drives & Inverter Drives: Interconnecting frequency converters and three-phase AC drive motors in automated plants.
• Public Infrastructure & Commercial Facilities: Airports, metro ventilation systems, hospitals, and high-rise buildings requiring LSZH fire reaction compliance.
• Heavy Industrial Processing & Conveyors: Powering automated production lines, pumps, fans, and compressors in tray and trunking layouts.
• High-Density Control & Electrical Rooms: Cable raceways located near sensitive telemetry, PLCs, and instrumentation networks requiring double screening.

Specifications & Dimensions

The 2XSL(st)CH LSZH cable portfolio encompasses standard 4-core layouts and symmetrical 3-core plus 3-split-earth conductor configurations, with nominal power conductor cross-sections extending from 1.5mm² up to 240mm² (delivering current carrying capacities up to 453A at 30°C continuous loading). Operating at a rated voltage of 0.6/1kV, the cable supports fixed installations from -30°C to +80°C and flexed movement from -5°C to +40°C, maintaining a minimum bending radius of 7.5× OD (fixed) and 15× OD (flexed). Conductor DC resistance values span from 13.3 Ω/km (1.5mm²) down to 0.0801 Ω/km (240mm²), with all overall diameters and weights strictly aligned with IEC 60502-1 and European harmonized standards.

Frequently Asked Questions

Q: What is the technical advantage of XLPE insulation over PVC in 2XSL(st)CH VFD cables?
A: XLPE provides a much lower dielectric loss factor and lower mutual capacitance than PVC, significantly reducing capacitive charging currents and preventing high-voltage reflection spikes (dV/dt) from stressing motor windings.

Q: How does the dual-layer screen (Al/PET tape + TCWB braid) protect industrial installations?
A: The Aluminium-polyester tape provides 100% coverage against high-frequency electromagnetic fields, while the heavy-duty tinned copper wire braid delivers low transfer impedance and mechanical robustness against low-frequency interference.

Q: Can the 2XSL(st)CH LSZH cable be installed directly in the ground?
A: Direct burial is not recommended; while the black outer sheath is UV-resistant and suited for outdoor tray and trunking runs, direct underground burial requires protective conduit or armored cable designs.

Q: What payment terms does Huadong Cable accept for international export contracts?
A: We provide standard international commercial terms including Telegraphic Transfer (T/T) and 100% Irrevocable Letter of Credit (L/C) at sight for engineering contractors and industrial drive system integrators.
