CY LSZH (HSLCH) Cable

What is CY LSZH (HSLCH) Cable?

The CY LSZH (HSLCH) cable is a low-voltage, unarmored and screened flexible multi-core control cable featuring Class 5 flexible plain copper conductors, LSZH insulation, a PET separator tape, a tinned copper wire braid (TCWB) screen, and a grey LSZH outer sheath complying with VDE 0207-303-7, IEC/EN 60332-1-2, and IEC/EN 60332-3-24 standards. It is designed for fixed wiring and free-moving flexible connection up to 300/500V in tooling machinery, automated assembly lines, and industrial control equipment without tensile load where electromagnetic protection and halogen-free fire safety are required.

Engineered to ensure interference-free signal and power transmission in sensitive industrial environments, the cable pairs an overall high-coverage TCWB braid with low smoke zero halogen polymer compounding. The braided screening system effectively intercepts external electromagnetic pulses and prevents internal harmonic radiation, while the halogen-free outer compound eliminates dense smoke and corrosive acid gases in the event of a fire, protecting delicate microelectronics and safeguarding evacuation corridors in public buildings and industrial plants.

CY LSZH (HSLCH) Cable Construction

• Conductor: Class 5 flexible stranded plain bare copper conductors per IEC/EN 60228 delivering superior electrical conductivity and dynamic flex fatigue resistance.
• Insulation: Low Smoke Zero Halogen (LSZH) thermoplastic compound engineered for dependable dielectric strength up to +80°C.
• Bedding / Separator: Polyester Tape (PET) separator applied over the assembled cores to ensure structural cohesion and smooth core movement.
• Screen / Armour: Tinned Copper Wire Braid (TCWB) providing comprehensive 360-degree electromagnetic compatibility (EMC) screening.
• Outer Sheath: Low Smoke Zero Halogen (LSZH) compound, flame retardant per IEC/EN 60332-1-2 and bunched fire test IEC/EN 60332-3-24.
• Core Identification: 2 cores: Black with White numbers; 3 cores and above: Black with White numbers + Green/Yellow protective earth conductor (colour-coded cores available upon request).
• Sheath Colour: Grey.

Applications

CY LSZH (HSLCH) cables are specifically designed for measuring, regulating, and controlling automated tooling machinery, conveyor systems, and production lines where electromagnetic interference (EMI) suppression and zero-halogen safety are mandatory. They are suitable for flexible use without tensile stress in dry, ambient, and wet indoor locations.

Typical installation environments include:

• Automated Tooling Machinery & Robotics: Flexible interconnection of multi-axis drives, sensors, and actuators near high-frequency noise sources.
• Public Buildings & Mass Transit: Control cabling in airports, metro stations, and hospitals where low smoke zero halogen emissions prevent toxic hazards.
• Industrial Control Panels & Switchgear: High-density cabinet interconnections and PLC lines requiring tight bend routing and EMC suppression.
• Data Centers & Server Rooms: Critical power and monitoring circuits located near sensitive electronic computing hardware vulnerable to acid corrosion.

Specifications & Dimensions

The CY LSZH (HSLCH) cable portfolio encompasses multi-core configurations from 2 cores up to 25 cores, with conductor cross-sections ranging from 0.5mm² to 35mm² supporting continuous current loading up to 135A at 30°C. Operating at a rated voltage of 300/500V, the cable supports fixed ambient temperatures from -40°C to +80°C and flexed moved installations from -15°C to +70°C, maintaining a minimum bending radius of 6× overall diameter for fixed installations and 15× overall diameter for flexible applications. Conductor DC resistance values span from 39 Ω/km (0.5mm²) down to 0.554 Ω/km (35mm²), with all core insulation thicknesses, outer sheath dimensions (from 5.4mm up to 28mm), and cable weights manufactured in strict accordance with VDE 0207-303-7 and European harmonized tolerances.

Frequently Asked Questions

Q: What is the technical difference between YY LSZH (HSLH) and CY LSZH (HSLCH) control cables?
A: While both use halogen-free insulation and sheath materials, CY LSZH includes an overall Tinned Copper Wire Braid (TCWB) screen over a PET separator to deliver electromagnetic compatibility (EMC) shielding against high-frequency electrical interference.

Q: Can CY LSZH (HSLCH) control cables be installed outdoors or buried underground?
A: No, CY LSZH cables are engineered specifically for indoor dry, ambient, and wet room applications; they are not intended for outdoor UV-exposed installations or direct underground burial.

Q: What are the minimum bending radius limits for CY LSZH flexible cables?
A: The cable requires a minimum bending radius of 6 times the overall diameter (6× OD) for fixed installations and 15 times the overall diameter (15× OD) for flexible, moved applications without tensile load.

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