SPECIAL CABLES FAQs
Click a question to reveal the answer.
- Chinese cable names are usually based on GB/T, JB/T, and national product standards. These names often describe the conductor, insulation, sheath material, fire performance, and application type in a Chinese coding system.
- International projects commonly use IEC standards, European harmonised codes, EN standards, CPR reaction-to-fire classes, or local market specifications. These systems may describe the same cable performance using a different naming method.
- For example, flexible rubber cables may be listed in China as YC or YZW type cables, while international buyers may be more familiar with H07RN-F. Flat lift or travelling cables may appear as TVVB / TVVBP in Chinese catalogues, while European catalogues may use H05VVH6-F or H07VVH6-F.
- The name does not need to be identical as long as the cable meets the required rated voltage, temperature class, bending radius, flame retardant performance, LSZH performance, oil resistance, UV resistance, screening structure, and installation standard.
- For international markets, the safest method is to provide a technical cross-reference table: Chinese standard reference, IEC / EN test method, cable construction, and project specification clause. This avoids the mistake of claiming that two names are automatically equal.
- No. Many special cables are standard catalogue products with fixed construction, conductor size, core number, insulation, sheath, and voltage rating.
- They are “special” because they are used in demanding applications such as cranes, elevators, industrial automation, fire alarm systems, marine panels, PV systems, or machine tools.
- True custom cables are only required when the buyer needs a non-standard combination of core arrangement, shielding, armour, compound, colour, voltage rating, or communication element.
- A single cable flame test checks how one cable behaves when exposed to flame.
- A bunched cable flame test checks how a group of cables behaves when installed together vertically or in cable trays.
- This is important because cables installed in groups create a larger fire load. A cable that performs well alone may behave differently when many cables are bundled together.
- For cable trays, risers, electrical rooms, and industrial routes, bunched flame performance is often more relevant than single wire flame performance.
- Flame retardant cable is designed to reduce flame spread. Its purpose is to prevent fire from propagating along the cable route.
- Fire resistant cable is designed to maintain circuit integrity for a defined time during fire.
- Fire resistant cables are used for emergency lighting, fire alarm circuits, smoke extraction systems, fire pumps, and other life safety systems.
- These two terms are not the same. A cable can be flame retardant without being fire resistant.
- Fire alarm cables often carry low voltage signals, but the circuit function is safety-critical.
- They may require controlled capacitance, stable impedance, twisted pairs, screening, LSZH sheath, or fire resistant construction.
- In long alarm loops, poor cable selection can cause signal instability, false alarms, or communication failure.
- For this reason, fire alarm cable selection should consider both electrical signal quality and fire performance.
- Pairs are usually used for two-wire signal circuits, differential signals, and many standard instrumentation loops.
- Triads are used where three-wire transmitters, RTD circuits, or specific measurement systems require three conductors grouped together.
- The choice affects noise rejection, wiring accuracy, termination method, and maintenance identification.
- For process plants, oil and gas facilities, and automation systems, correct pair or triad selection helps reduce signal errors.
- XLPE insulation has better thermal performance than many standard thermoplastic insulation materials.
- It offers good electrical properties, ageing resistance, and temperature stability.
- XLPE is often selected where the cable may face higher operating temperature, overload conditions, or long service life requirements.
- For instrumentation and control circuits, XLPE can also support stable insulation performance in demanding industrial environments.
- VFD motor cables are used between variable frequency drives and motors. They must handle fast switching waveforms, harmonics, and high dv/dt stress.
- Poor cable selection can cause motor insulation stress, bearing currents, EMC interference, and unstable control signals nearby.
- Special VFD cables often use symmetrical grounding conductors, low impedance screens, or dual shield structures.
- Cable length, drive output waveform, motor insulation, and grounding design must be considered together.
- Solar DC cables are exposed to outdoor conditions for many years.
- They must resist UV radiation, ozone, temperature cycling, moisture, and mechanical handling during installation.
- Solar cables also operate in DC systems, where arc behaviour and insulation performance are different from many AC circuits.
- Ordinary flexible cords should not be used as a substitute for PV string cable unless the required DC voltage, outdoor durability, and standard compliance are fully proven.
- Outdoor flexible cables can fail because of UV exposure, ozone attack, temperature cycling, abrasion, and repeated bending.
- The most common problems are sheath cracking, conductor fatigue, insulation damage, and water ingress.
- For cranes, festoon systems, outdoor machinery, and temporary power routes, the cable must match the required bend radius, flex cycle, tensile load, and outdoor rating.
- “Outdoor cable” should not be selected only by colour or sheath thickness.
- Lift travelling cables are designed for repeated vertical movement.
- They require controlled flat geometry, flexibility, strain relief, and sometimes integrated support elements.
- Incorrect installation can cause twisting, uneven tension, conductor breakage, or sheath damage.
- Important checks include suspension length, bending radius, tension control, core arrangement, and compatibility with lift travelling systems.
- Wind turbine cables may face torsion, vibration, temperature changes, UV exposure, and lightning-related transients.
- Tower cables and nacelle cables require strong mechanical anchoring and careful route planning.
- Cable replacement can be difficult, so long-term durability is important.
- Selection should consider flexibility, screen continuity, grounding, sheath resistance, and maintenance access.
There are different types of special low-voltage cables. Among the Chinne range you can find cables for audio-visual use, for mobile service, alarm systems and for lifts, cranes, hoists or transport systems.
The choice of the best cable depends on the characteristics of each project. The suitability of the cable will be determined by the correct choice according to the needs of the installation.
Low voltage cables operate at voltages up to 1 kV (1,000 volts) and are used for residential, commercial and light industrial applications. High-voltage cables, on the other hand, are designed for voltages above 1 kV, typically ranging from 1 kV to 765 kV or higher, and are used to transmit electricity over long distances and in high-demand industrial applications.
While standard LV cables are suitable for general use, low voltage special cables are tailored for specific needs and environments, offering enhanced performance and protection.
Choosing the right special cable for your application involves several important considerations. Determine the voltage level required for your application, considering factors like the length of the cable run and the ambient temperature, as these can affect the cable’s performance, choose the appropriate insulation material based and the best conductor material. Beyond that, it is necessary to assess the specific performance required by the installation.
