Building Wires Manufacturers

What We Manufacture in This Category

Our Infrastructure & Construction Cables family is built around two product lines: PVC-insulated cables, wires and cords, and environmentally friendly wires and cables for fixed wiring. Both are manufactured as standard models and as customised constructions based on drawings or samples, with conductor, insulation, core count, sheath colour and special performance requirements agreed before production.

The range is positioned for lighting circuits, socket outlets, distribution boards, control and instrumentation wiring, and internal power distribution inside buildings. It is not a single cable type but a configurable family: the same conductor size can be supplied with PVC or cross-linked polyolefin insulation, with or without mica fire barrier, and with different sheath compounds depending on the installation environment.

Our Infrastructure & Construction Cable Range

Conductor, Insulation and Construction Options

Conductors are supplied as Class 1 solid, Class 2 round stranded or Class 5 flexible copper, and as aluminium or aluminium alloy where weight or cost balance matters. PVC-insulated models use PVC insulation and PVC sheathing compound; environmentally friendly models use cross-linked polyethylene, polyolefin or cross-linked polyolefin insulation with low-smoke halogen-free tape and polyolefin or cross-linked polyolefin sheath.

• Conductor classes: Class 1, Class 2 and Class 5 copper; Class 1 and Class 2 aluminium and aluminium alloy.
• Fire barrier: mica tape refractory layer available on fire-resistant constructions.
• Filling and wrapping: non-hygroscopic polypropylene filler rope, non-woven fabric, polyester tape or low-smoke halogen-free tape.
• Shielding: copper wire braid available on environmentally friendly multicore constructions.
• Sheath colour: white, black or customer-specified.
• Special performance: flame retardant A/B/C grade, fire resistant, termite resistant, rodent resistant, UV resistant, low temperature resistant and mineral oil resistant.

Critical Specifications and Operating Limits

For PVC-insulated cables, the maximum long-term conductor temperature is 70°C, with a short-circuit allowance of 160°C for no more than 5 seconds. Environmentally friendly constructions raise the continuous rating to 90°C for cross-linked polyethylene or cross-linked polyolefin insulation, with a 250°C short-circuit limit; polyolefin-insulated versions remain at 70°C and 160°C.

Core Identification and Installation Practice

Coloured insulation uses one colour per core except the green/yellow combination, which must cover 30–70% of the core surface. Preferred colour sequences are green/yellow, blue, brown for three-core; green/yellow, brown, black, grey or blue, brown, black, grey for four-core; and green/yellow, blue, brown, black, grey for five-core. Cables with six or more cores are numbered, with black insulation and white digits recommended, spaced no more than 50 mm between number groups.

Installation is by fixed wiring indoors or outdoors, or embedded in conduit or a similar closed system. We supply installation guidance covering bending radius, conduit protection, cable securing and separation of power and signal circuits so that the installed cable performs within its rated conditions.

Quality Control and Manufacturing Capability

Henghui Cable operates two production zones and nine specialised workshops across approximately 200,000 m², with more than 20 production lines and annual output exceeding 50,000 km. An MES system provides end-to-end digital control from raw material intake to finished product, and our R&D team is led by more than 30 senior engineers supported by a quality assurance team of over 20 professionals.

Quality management, environmental management and occupational health and safety management systems have been certified since 2006. The company holds TÜV Rheinland solar PV cable certification, CE and EAC, and has been recognised as a Jiangsu Provincial Green Factory with carbon footprint certification and national greenhouse gas verification. Every batch of construction cable is tested for insulation quality and electrical safety before dispatch.

Information We Use to Configure Your Solution

To prepare an accurate configuration and quotation, we work from the following project inputs. Where a project specifies a standard, we confirm the applicable implementation standard before production.

• Model and specification: cable model, conductor size, core count and voltage level.
• Quantity: total metres per size and any staged delivery requirements.
• Technical standard: GB/T5023-2008, JB/T8734-2016, Q/320282DJD006-2021 or a project-specific standard.
• Installation environment: indoor or outdoor, conduit-embedded, wet or corrosive locations, ambient temperature range.
• Special performance: flame retardant grade, fire resistance, termite, rodent, UV, low temperature or oil resistance.
• Identification and sheath: core colour sequence, digital identification and sheath colour.
• Packaging and delivery: drum or coil format, marking, and destination port or site.

Related Cable Categories

Infrastructure and construction wiring is one part of our cable programme. Projects that combine building wiring with distribution, control or renewable energy circuits can be supplied across our other ranges: Power Grid Transmission & Transformation Cables, Industrial Cables, Rail & Transit Cables and New Energy Cables.

Frequently Asked Questions

What is the difference between the PVC-insulated and environmentally friendly ranges?

The PVC range uses PVC insulation and sheath, rated to 70°C continuous, and is suited to general lighting, socket and fixed wiring. The environmentally friendly range uses cross-linked polyethylene or cross-linked polyolefin insulation with low-smoke halogen-free materials, rated to 90°C continuous, and is specified for rail transit, airports, hospitals, high-rise buildings and shopping malls where smoke and halogen emissions must be limited.

Can you manufacture to our project standard rather than a catalogue model?

Yes. We produce both standardised and customised cables, developing constructions from customer drawings or samples. Conductor class, insulation compound, core count, colour sequence, sheath material and special performance requirements can all be fixed to the project specification.

What is the minimum order quantity and delivery time?

Minimum order quantity varies by product; most items have a minimum of 200 metres. Typical delivery time is about 7 to 10 days, and our ERP-supported warehousing network supports international shipment within a week for stocked items.

What warranty and after-sales support do you provide?

Products carry a one-year warranty. Our after-sales team covers the full process from pre-service to after-service and conducts regular customer satisfaction follow-ups.

Which standards do your construction cables follow?

PVC-insulated cables, wires and cords are produced to GB/T5023-2008 and JB/T8734-2016. Environmentally friendly fixed wiring cables follow Q/320282DJD006-2021. Where a project requires another standard, we confirm the applicable specification before production.
