❓ Frequently Asked Questions (FAQ)

Q1: What is a special cable?
A: A special cable (特种电缆) is a cable designed for specific applications and demanding environments where standard cables cannot perform reliably. Special cables have unique properties such as high-temperature resistance, flame retardancy, oil/chemical resistance, ultra-flexibility, low smoke halogen free, anti-termite, or radiation resistance[reference:35][reference:36]. They are used in aerospace, nuclear power, marine, mining, petrochemical, and other specialized industries[reference:37].

Q2: What are the main categories of special cables?
A: Main categories include: High-temperature cables (-60°C to +400°C), Flame retardant cables (ZR, ZRA, NH), Low smoke halogen free cables (WDZ, LSZH), Oil and chemical resistant cables, Ultra-flexible drag chain cables, Marine cables, Nuclear power cables, Mining cables, Anti-termite cables, and Flat/ribbon cables[reference:38].

Q3: What standards do your special cables comply with?
A: We manufacture special cables in compliance with IEC (international), GB/T and JB (Chinese national), BS (British), DIN and VDE (German), JIS (Japanese), ANSI (American), and MIL (military) standards[reference:39]. We also support project-specific custom standards upon request.

Q4: What is the difference between flame retardant (ZR) and fire resistant (NH) cables?
A: ZR (Flame Retardant) cables are designed to prevent flame propagation and self-extinguish when the ignition source is removed[reference:40]. NH (Fire Resistant) cables are designed to maintain circuit integrity during a fire for a specified period (typically 90-180 minutes), ensuring critical systems (fire alarms, emergency lighting, safety systems) continue to operate[reference:41].

Q5: What is the difference between LSZH and PVC cables?
A: LSZH (Low Smoke Halogen Free) cables emit very low smoke and no toxic halogen gases when burned, making them essential for enclosed spaces, tunnels, and populated areas[reference:42]. PVC cables emit dense smoke and toxic gases (HCl) when burned. LSZH cables are required in rail vehicles, ships, tunnels, and buildings where human safety is critical[reference:43].

Q6: What is the temperature range for high-temperature special cables?
A: Temperature range depends on insulation/sheath materials: PVC/PE: -40°C ~ +70°C; XLPE: -40°C ~ +90°C; Silicone: -60°C ~ +180°C; PTFE/FEP: -60°C ~ +200°C; Glass Fiber: -60°C ~ +400°C. Special high-temperature cables can withstand up to +400°C for continuous operation[reference:44].

Q7: What are the typical applications of special cables in EPC projects?
A: Special cables are widely used in EPC projects for: Power plants — high-temperature and fire-resistant cables for boiler and turbine areas; Petrochemical plants — oil/chemical resistant cables; Mining projects — abrasion resistant flexible cables[reference:45]; Marine and offshore — salt water and flame resistant cables; Nuclear power — radiation resistant cables[reference:46]; Rail and transit — LSZH flame retardant cables[reference:47].

Q8: What is a low smoke halogen free (LSZH) cable?
A: LSZH (Low Smoke Halogen Free) cable, also known as WDZ (无卤低烟) cable, is a special cable that emits very low smoke and no toxic halogen gases when exposed to fire[reference:48]. It uses halogen-free compounds for insulation and sheath, making it safe for human occupancy in enclosed spaces. LSZH cables are mandatory in tunnels, subways, ships, high-rise buildings, and data centers.

Q9: What is an intrinsically safe (IA) cable?
A: IA (Intrinsically Safe) cables are specially designed for hazardous areas where flammable gases or dust may be present[reference:49]. They are used in DCS (Distributed Control Systems) and instrumentation circuits in petrochemical, oil & gas, and mining applications. These cables have low capacitance and inductance to prevent sparking and ignition in explosive environments.

Q10: What are military specification (MIL) cables?
A: MIL spec cables are manufactured to US military standards for extreme reliability and performance[reference:50]. Common types include: MIL-W-81044 and MIL-W-22759 — high-temperature (150~200°C) wires with tin, silver, or nickel plated conductors and fluoropolymer insulation[reference:51]; MIL-C-27500 — shielded cables with multiple conductors for aerospace and defense applications[reference:52].

Q11: What are flat/ribbon special cables used for?
A: Flat/ribbon cables are used in moving equipment where space is limited and flexibility is required[reference:53]. Common applications include: Elevators and lifts — control and power transmission with steel wire support for tension[reference:54]; Cranes and hoists — flat cables with high mechanical strength[reference:55]; Robotics and automation — space-saving ribbon cables for signal and power[reference:56].

Q12: What is the difference between armored and unarmored special cables?
A: Unarmored cables are suitable for indoor installations, cable trays, and conduits where mechanical protection is not critical. Armored cables (22 — steel tape, 32 — steel wire) have a metal armor layer providing mechanical protection against crushing, impact, tension, and rodents. Armored cables are required for direct burial, underground trenches, and harsh industrial environments.

Q13: What conductor materials are available for special cables?
A: We offer multiple conductor options: Copper — standard for most applications; Tinned Copper — improved corrosion resistance[reference:57]; Silver-Plated Copper — for high-temperature applications up to 200°C; Nickel-Plated Copper — for extreme temperatures up to 400°C; and Stranded conductors for flexibility in moving applications.

Q14: What special cables are used in nuclear power plants?
A: Nuclear power plants require radiation resistant cables that can withstand high radiation doses without degradation[reference:58]. Key requirements include: LOCA (Loss of Coolant Accident) testing — cables must function during and after a design-basis accident; 60-year design life — cables must maintain performance over the plant's operating life; Low smoke and flame retardant — for fire safety; Qualification to IEEE 383 or RCC-E standards.

Q15: What are heat tracing cables used for?
A: Heat tracing cables (电伴热带) are special cables used to maintain or raise the temperature of pipes, tanks, and equipment[reference:59]. Common types include: Constant power series (HWL/HCL) — for long pipelines and freeze protection[reference:60]; Self-regulating cables — automatically adjust heat output based on temperature. Applications include pipe freeze protection, process temperature maintenance, and roof/gutter de-icing in power plants, petrochemical, and oil & gas facilities.

Q16: What tests are performed on special cables before delivery?
A: We conduct comprehensive quality tests including: (1) Electrical tests — conductor resistance, insulation resistance, voltage withstand; (2) Mechanical tests — tensile strength, elongation, bending, impact, abrasion; (3) Thermal tests — temperature cycling, heat aging; (4) Flame tests — per IEC 60332 series, UL VW-1, IEEE 1580[reference:61]; (5) Chemical tests — oil resistance, acid/alkali resistance; (6) Special tests — radiation resistance, water blocking, termite resistance based on project requirements.
