High-Temperature Cables

A high-temperature cable is a special cable that operates stably for long periods in high-temperature environments. Its key characteristics and applications focus on demanding temperature scenarios. In terms of characteristics, **temperature resistance is the core**: continuous operating temperature of -60 °C to +260 °C, with special types (such as silicone rubber or fluoroplastic insulation) reaching 400 °C; the insulation layer does not soften at high temperatures and electrical performance remains stable. It also combines weather resistance (UV and salt spray resistance) with corrosion resistance (acid, alkali and oil resistance), achieves flame retardance to UL94 V-0, and has high mechanical strength without becoming brittle. Applications focus on high-temperature working conditions: industry (power supply for metallurgical kilns and glass production lines), new energy (wiring in high-temperature areas of PV inverters and energy storage systems), aerospace (cables around engines) and chemical plants (monitoring cables for high-temperature reactors), ensuring continuous power supply and signal transmission for equipment under extreme heat.

LSZH Cables

Low-smoke, halogen-free (LSZH) cable uses halogen-free flame-retardant material as the insulation/jacket, and its core advantage centers on safety plus environmental friendliness. Its characteristics and applications are as follows. In terms of characteristics, **low smoke and low toxicity are the key**: when burning, smoke light transmittance ≥ 80% does not block visibility, and toxic gases such as hydrogen chloride released are ≤ 5 mg/g, reducing harm to people. Environmentally friendly and halogen-free: contains no halogens such as chlorine or bromine, complies with RoHS/REACH standards, and leaves no pollutants after disposal. It is also flame retardant to UL94 V-0, with good weather resistance against UV and damp heat, and mechanical strength that meets cabling needs. Applications focus on high-safety scenarios: enclosed transit spaces such as subways and high-speed rail, crowded venues such as hospitals and shopping malls, critical facilities such as data centers and equipment rooms, plus renewable power stations and green buildings, meeting the dual requirements of safety and environmental friendliness.

Ultra-Flexible Cables

Ultra-flexible cable uses multiple fine copper wires as conductors with TPE/TPU insulation, and its core advantage is extreme flexibility. Its characteristics and applications are as follows. In terms of characteristics, **extremely strong flexibility**: bend radius ≤ 5 times the cable outer diameter, dynamic flex life of over one million cycles, and resistance to repeated folding and twisting without breaking. Wide temperature adaptability (-40 °C to +105 °C): not brittle at low temperatures and not stiff at high temperatures. It also combines wear resistance and tear resistance to withstand frequent dragging, is halogen-free and environmentally friendly in compliance with RoHS, and some types support sterilization. Applications focus on high-frequency motion and tight spaces: industry (robot joints, machine tool drag chains), medical equipment (minimally invasive surgical instruments, portable patient monitors), consumer electronics (VR devices, foldable phone flex cables) and precision cabling on automated production lines, ensuring stable power supply and signal transmission in dynamic scenarios.

Torsion-Resistant Cables

A torsion-resistant cable is designed specifically for high-frequency twisting scenarios, and its core advantage is resistance to torsional fatigue. Its characteristics and applications are as follows. In terms of characteristics, **outstanding torsion resistance**: with stranded conductors of fine copper wires plus a spiral-wrapped construction, it achieves a twist life of over one million cycles (e.g., repeated ±360° twisting) without the conductors and insulation layer breaking during twisting. Flexible adaptation: bend radius ≤ 5 times the outer diameter, covering twisting and bending requirements simultaneously. Temperature range -40 °C to +105 °C, wear and tear resistant, with the insulation layer maintaining stable electrical performance during twisting. Mostly made of halogen-free, environmentally friendly materials in compliance with RoHS. Applications focus on dynamic twisting scenarios: industrial robots (power supply for multi-joint rotation), automation equipment (rotary worktable cables), surgical robots (twisting cable routing in robotic arms) and construction machinery (rotary arm connections), ensuring continuous power supply and signal transmission under frequent twisting.

CPR Flame-Retardant Cables

CPR flame-retardant cable refers to cable that complies with the EU Construction Products Regulation (CPR 305/2011/EU) and EN 50575, and its core advantage is precisely graded fire safety performance. In terms of characteristics, cables are classified into seven classes from Aca to Fca according to heat release and flame spread rate. Class Aca is nearly non-combustible with extremely limited flame propagation. It also features low smoke and low toxicity, with smoke density and acidic gas emissions meeting EN 61034-2 and EN 60754-2, and restricted halogen content. It also provides basic mechanical strength and insulation stability, suiting fixed building wiring needs. Applications focus on high-safety scenarios: Class Aca is used in nuclear power plants and core areas of data centers; B1ca/B2ca classes suit crowded buildings such as shopping malls and hospitals; Class Cca and below are used in ordinary residential and industrial premises. CPR compliance is also a mandatory requirement for market access of building cable in the EU.
