Veriflex Screened Bedded LSZH Cable

What is Veriflex Screened Bedded LSZH Cable?

The Veriflex Screened Bedded LSZH Cable is a low-voltage (300/500V), halogen-free, screened multi-core flexible connecting and control cable designed in compliance with VDE 0295, VDE 0207-303-7, and VDE 0819-102 standards. It is engineered for signal transmission, process regulation, and power feeding across tooling machinery, industrial production lines, and mechanical assembly equipment.

Constructed specifically for flexible indoor operation involving free movement without tensile loads, this cable features a dual-layer polymer build incorporating a specialized LSZH inner bedding layer underneath a tinned copper wire braid (TCWB). The inner bedding provides substantial crush and impact resistance, protecting internal core insulation from mechanical pressure, while the high-density TCWB shield blocks external high-frequency electrical interference pulses and electromagnetic radiation. In the event of a fire, its LSZH insulation and jacket produce negligible smoke (IEC/EN 61034) and release zero corrosive halogen acid gases (IEC/EN 60754), meeting IEC/EN 60332-3-24 bunched fire propagation standards to safeguard human life and technical equipment.

Applications

Veriflex Screened Bedded LSZH Cables are engineered for fixed wiring and free-moving flexible links across modern industrial control circuits and instrumentation equipment:

• Machine Tool & Production Line Wiring: Flexible interconnect cabling for CNC machinery, packaging apparatus, and multi-axis assembly robots operating in dry, moist, or wet indoor conditions.
• Control & Instrumentation Cubicles: Jumper cabling between terminal blocks, motor drives, PLCs, and remote operator panels sensitive to electromagnetic interference.
• Industrial HVAC & Conveyor Systems: Drive control lines subject to constant operational vibration without external tensile load.
• Public Infrastructure & Clean Facilities: Airport logistics centers, data halls, and commercial manufacturing plants where bunched flame retardancy (IEC/EN 60332-3-24) and zero-halogen fire safety are mandatory.

Specifications & Dimensions

The Veriflex Screened Bedded LSZH cable series spans multi-core configurations from 2 to 25 cores with nominal conductor cross-sections from 0.5 mm² to 35 mm². Designed for a rated operating voltage of 300/500V, the cable operates across temperature ratings of -40°C to +80°C (fixed) and -15°C to +70°C (flexed), requiring a minimum bending radius of 6× overall diameter for fixed installations and 15× overall diameter for flexible movement. Nominal overall diameters range from 6.8 mm (2 × 0.5 mm²) up to 30.4 mm (4 × 35 mm²), with nominal weights spanning 77 kg/km to 2096 kg/km. Conductor DC resistance at 20°C ranges from 39.0 Ω/km (0.5 mm²) down to 0.554 Ω/km (35 mm²), delivering continuous 30°C current ratings between 9A and 135A per VDE standards.

Frequently Asked Questions

Q: What is the mechanical role of the inner bedding layer in this Veriflex cable?
A: The extruded LSZH bedding layer forms a protective barrier over the core bundle, cushioning the insulated conductors against external mechanical compression, dampening vibration, and preventing the braid wires from chafing the primary core insulation during cable flexing.

Q: Can Veriflex Screened Bedded LSZH cables be installed outdoors or directly buried underground?
A: No, these cables are specifically designed for interior installation in dry, moist, and wet rooms; they are not rated for outdoor UV exposure without protective conduit, nor are they approved for direct underground burial.

Q: What fire safety certifications apply to this screened control cable?
A: The cable is tested to IEC/EN 60332-1-2 and bunched fire test IEC/EN 60332-3-24; its halogen-free LSZH materials generate zero corrosive acid gases per IEC/EN 60754 and low smoke per IEC/EN 61034, conforming to European CPR EN 50575 regulations.

Q: What payment terms does Huadong Cable accept for international industrial export orders?
A: We accept standard international commercial payment terms, including Telegraphic Transfer (T/T, 30% advance deposit and 70% against shipping documents) and 100% Irrevocable Letter of Credit (L/C) at sight.
