Electric Cable Types and Applications: A Technical Reference for Global Industrial Buyers

Selecting the correct electric cable is critical for project safety, performance, and compliance. However, the wide variety of cable types, insulation materials, and industry standards can make procurement complex. This guide provides a structured overview of electric cable categories, their typical applications, and key selection parameters, drawing on the product expertise of Shanghai Shenghua Cable Group Co., Ltd., a major Chinese manufacturer founded in 1997.

Problem Definition

Industrial buyers often face difficulty distinguishing between cable types (e.g., XLPE vs. PVC insulated, armored vs. unarmored) and matching them to specific project environments. Without clear technical criteria, the wrong cable choice can lead to electrical failures, safety hazards, and non‑compliance with international standards.

These cables are used in automated assembly lines, DCS (Distributed Control Systems), power plant monitoring, and monitoring station projects, connecting PLC controllers to actuators and sensors (corpus ids: 15, 16).

Rubber Sheathed Cables

This product is a Rubber Sheathed Cable. Available model designations include YC/YCW and YZ/YZW, rated at 300/500 V or 450/750 V. The product’s role is to provide flexible power connection for portable or moving equipment. It is used in construction sites, ports, and household appliances, including temporary power supply and heavy‑duty mobile equipment projects (corpus ids: 9, 10, 11, 12).

Solar Photovoltaic Cables

This product is a Solar Photovoltaic Cable, classified as a Solar Photovoltaic Cable. The model is identified as PV1‑F, covering 600 V to 1500 V DC. It is used in the renewable energy and solar PV industry for connecting solar panels to string boxes or inverters, suitable for ground‑mounted PV plants, commercial rooftops, and floating solar arrays (corpus ids: 13).

Mining Cables

Shenghua Cable offers mining cables with models such as MFVP, MYP, and MCPT, rated at LV (0.6/1 kV) and MV (3.6/6 kV, sometimes 6/10 kV). These are applied in mining operations, underground and surface mining equipment, including coal mining and metal mining (corpus id: 27).

Marine Cables

This product is Marine Cables. Model designations include MFVP, MYP, and MCPT. It is suitable for cargo ship, cruise liner, and offshore oil rig/FPSO projects. Voltage ranges from LV to MV (0.6/1 kV, 3.6/6 kV) depending on shipboard systems (corpus ids: 2, 24).

Mineral Insulated Cables

Mineral insulated cables (models BTTZ, BTTRZ, BTLY) are used for fire‑resistant wiring, high‑temperature industrial equipment, and critical power systems. The product’s role is to ensure circuit integrity during a fire to save lives. It is used in high‑rise landmarks, hospitals, museums, and historic buildings, suitable for fire emergency systems and high‑temperature industrial zone projects (corpus ids: 4, 6, 7).

Overhead Conductors

Overhead conductors include models AAC, ACSR, ABC, and AAAC, typically used for overhead power lines and utility transmission networks. Voltage ranges from LV to MV (0.6/1 kV to 35 kV), with some high‑voltage types above 66 kV.

Step‑by‑Step Cable Selection Guide

1. Identify project environment: Determine whether the cable will be installed indoors, outdoors, underground, in high‑temperature zones, or in explosive atmospheres.
2. Assess voltage requirements: Match the cable’s rated voltage (e.g., 0.6/1 kV, 3.6/6 kV, 290/500 kV) to the system voltage.
3. Choose conductor material: Copper (hard or flexible) for higher conductivity; aluminum for lighter weight and cost savings.
4. Select insulation & sheath: XLPE for higher temperature and voltage ratings; PVC for general purpose; EPR/rubber for flexibility; LSZH for fire‑safety; mineral insulation for fire‑resistance.
5. Decide on armoring: SWA (steel wire), DSTA (double steel tape), or steel wire braided for mechanical protection; water‑blocked for wet conditions.
6. Verify certifications: Ensure the supplier holds relevant international certifications (e.g., CE, KEMA, IEC) if required by the project.

Use Cases Across Industries

• Power Utilities & Infrastructure: Use XLPE insulated power cables (YJV series) for substations and grid expansion.
• Industrial Automation & Oil & Gas: Use control & instrumentation cables (KVV, KVVP) for DCS and sensor networks.
• Construction & Commercial Buildings: Use building wires (BV, BVV) for final circuit distribution.
• Renewable Energy (Solar PV): Use PV1‑F solar cables for DC connections in photovoltaic systems.
• Marine & Offshore: Use marine cables (MFVP, MYP) for ships and oil rigs.
• Fire Protection & High‑Temperature Areas: Use mineral insulated cables (BTTZ) for emergency circuits.
