Introduction

As one of the leading wire and cable manufacturers, the industry plays a vital role in powering modern infrastructure and enabling global communication. Wires and cables are designed to transmit electrical power and electromagnetic signals, serving as the "blood vessels" and "nervous system" of today's power grids, communication networks, industrial facilities, and intelligent manufacturing systems.

Whether for power transmission, renewable energy, telecommunications, or industrial automation, selecting the right cable solution is essential for safety, efficiency, and long-term reliability.

Core Definition and Distinction

Essential Function

The primary function of wires and cables is to transmit electrical power (strong current) or signals and information (weak current), enabling efficient electrical and electromagnetic energy transmission.

Difference Between Wires and Cables

There is no strict physical distinction between a wire and a cable.

Generally:

• Wire refers to products with fewer cores, smaller diameters, and simpler structures, including bare conductors.
• Cable generally refers to products with multiple cores, larger diameters, and more complex constructions incorporating insulation and protective jackets.

Today, both are commonly referred to as wire and cable products.

Basic Structure

A typical cable consists of:

• Conductor
• Insulation Layer
• Shielding Layer (when required)
• Protective Sheath

Some industrial cables also include fillers, armor, water-blocking materials, and specialized shielding for demanding environments.

Main Categories of Wires and Cables

1. Bare Conductors

Bare conductors consist solely of conductive materials without insulation, such as Aluminum Conductor Steel Reinforced (ACSR), primarily used in overhead transmission lines.

2. Power Cables

Power cables transmit high-voltage and high-current electricity throughout generation, transmission, distribution, and utility networks.

3. Electrical Equipment Wires

Including building wires (BV, BVR) and flexible cables (RVV), these products are widely used in residential wiring, commercial buildings, machinery, and electrical equipment.

4. Communication and Fiber Optic Cables

Designed for voice, video, and high-speed data transmission, including:

• Twisted-pair cables
• Coaxial cables
• Fiber optic cables

These products support broadband networks, 5G infrastructure, and modern data centers.

5. Magnet (Winding) Wires

Used in motors, transformers, generators, inductors, and other electromagnetic equipment.

Key Materials

Conductors

Most cables utilize high-purity copper or aluminum conductors, providing excellent electrical conductivity and energy efficiency.

Insulation and Jacket Materials

Common materials include:

• PVC
• PE
• XLPE

These materials provide excellent insulation while offering resistance to flame, heat, moisture, chemicals, and mechanical wear.

Components of Wires and Cables

A standard wire or cable consists of four primary components.

Conductor

The conductor carries electrical current or communication signals and forms the core of the cable.

Insulation Layer

The insulation separates conductors electrically, ensuring safe and reliable power transmission.

Shielding Layer

Power cables rated above 15 kV typically include conductor and insulation shielding to improve electrical field distribution and reduce interference.

Protective Layer

The outer sheath protects against moisture, chemicals, abrasion, impact, UV exposure, and environmental damage.
