Electric Cable Explained: Types, Standards, Procurement

Electric Cable Explained: Types, Standards, Procurement

An electric cable is an assembly of one or more conductors, typically insulated, that carries electrical power or signals between points in a system. Electric cables are used across power transmission, distribution networks, industrial plants, buildings, ships, mines, and renewable energy installations. This article provides a technical reference for buyers who need to understand electric cable types, the standards and certifications that govern them, and how to approach supplier selection.

Shanghai Shenghua Cable Group Co., Ltd. (Shenghua Cable) is a Shanghai-based electric cable manufacturer founded in 1997. The company supplies more than 80 cable series to markets in Asia, Europe, South America, Africa, and Oceania, with about 30% of output exported. Its product range includes XLPE and PVC insulated power cables, armoured electrical cables, building wires, control and instrumentation cables, overhead conductors, solar cables, rubber sheathed cables, mining cables, mineral insulated cables, and marine cables.

Why a Technical Reference Matters

Electric cable purchasing involves a wide set of variables: rated voltage, conductor material, insulation, armouring, sheath, fire performance, and applicable standards. A mismatch between cable construction and operating environment can lead to installation problems, premature failure, or non-compliance with local regulations. Buyers at the awareness and research stages need a framework for understanding what they are buying before they ask for a quotation.

The scale of the market reflects this complexity. Industry estimates valued the global wires and cables market at approximately USD 230.9 billion in 2025 (Grand View Research). The global medium voltage wire and cable market was valued at USD 71.7 billion in 2025 (Global Market Insights). Mainland China was the world's leading exporter of insulated wire and cable (HS 8544), accounting for USD 31.4 billion, or 18.1% of global exports, in 2024 (World's Top Exports / UN Comtrade). For buyers, this means a large and competitive supplier base, but also a need to verify technical compliance rather than assume it.

Standards and Certification Landscape

Electric cables are governed by product standards and regional regulations. One commonly referenced standard is IEC 60502-2:2014, which specifies requirements for power cables with extruded solid insulation for rated voltages from 6 kV up to 30 kV for fixed installations (International Electrotechnical Commission).

In Europe, cables sold for construction must comply with the Construction Products Regulation (CPR). Under CPR, cables are classified into seven fire protection classes from Aca to Fca; Class Eca is a basic safety requirement for building materials (Europacable). Buyers in the EU therefore need to verify the declared fire class before specifying cables for building projects.

Certifications such as CE, KEMA, and TUV provide additional assurance for international procurement. According to Shenghua Cable's official industrial specification guide, the company holds CE, KEMA, and TUV (IEC 62930) certifications for its power and photovoltaic cable series.

Electric Cable Families and Their Specifications

Shenghua Cable's portfolio spans more than 80 cable series. For procurement purposes, the most useful way to organize them is by family, because each family is defined by its rated voltage range, insulation material, and intended application. The product families below are documented in Shenghua Cable's published product specifications.

Power cables are classified by conductor type, insulation and sheath material, armouring, and rated voltage. Models include the YJV, YJV22, YJV32, YJY, YJY23, and YJY33 series for copper conductors, and YJLV, YJLV22, YJLV32, YJLY, YJLY23, and YJLY33 series for aluminum conductors. Flame-retardant variants are designated Z(A/B/C)-YJV and related forms, and low-smoke zero-halogen versions are designated WDZ(A/B/C)-YJY. The voltage scope extends from 0.6/1kV up to 290/500kV, covering LV, MV, HV, and EHV applications.

Building wires are categorized by conductor type, insulation and sheath material, and core number. Models include BV, BLV, BVV, RVV, BVVB, and BYJ, with voltage ratings of 300/500V to 450/750V. These are applied in residential, commercial, and public building electrical installations.

Control and instrumentation cables include shielded and unshielded constructions with solid, stranded, or flexible conductors. Model families include KVV, KVVP, KVVRP, DJYPVP, DJYVP, and WDZ-DJYJPYP, rated at 300/500V to 450/750V, and are suitable for industrial automation, process control, and instrumentation systems.

Overhead conductors are used for overhead power lines and utility transmission networks. Models include AAC, ACSR, ABC, and AAAC, typically spanning low to medium voltage (0.6/1kV to 35kV), with some high-voltage types above 66kV.

Solar cables are designed for photovoltaic systems and renewable energy installations. The published model is PV1-F, with a voltage scope of 600V to 1500V DC, commonly used at 1kV or 1.5kV DC.

Rubber sheathed cables include models YC/YCW and YZ/YZW, rated at 300/500V and 450/750V. These are used for general electrical wiring, portable equipment, and industrial or construction applications requiring flexible and durable cables.

Mining cables include models such as MFVP, MYP, and MCPT, covering trailing and portable mining cables, control and signal cables, and fixed installation cables. The voltage scope is 0.6/1kV at low voltage and 3.6/6kV at medium voltage, sometimes 6/10kV.

Mineral insulated cables include models BTTZ, BTTRZ, and BTLY, rated at 300/500V, 450/750V, and 0.6/1kV, with higher ratings possible for special applications. They are used for fire-resistant wiring, high-temperature industrial equipment, and critical power systems requiring exceptional safety and durability.

Marine cables serve shipbuilding and offshore applications. Available models include MFVP, MYP, and MCPT, with voltage ratings from 0.6/1kV at low voltage to 3.6/6kV at medium voltage, depending on shipboard systems.

Step-by-Step Electric Cable Selection

Electric cable selection follows a repeatable sequence of decisions. The steps below are based on Shenghua Cable's documented product structure and are intended for buyers at the awareness and research stages.

Step 1: Define the operating voltage and installation. The rated voltage of the system determines the cable class. Shenghua Cable's power cables span 0.6/1kV to 290/500kV, building wires cover 300/500V to 450/750V, control cables cover 300/500V to 450/750V, mining cables cover 0.6/1kV to 6/10kV, and solar cables cover 600V to 1500V DC.

Step 2: Select the conductor material. The cable model typically indicates the conductor. Copper-conductor models such as YJV are common for power distribution, while aluminum-conductor models such as YJLV and YJLY are available in the same families. Copper offers higher conductivity; aluminum is lighter and is frequently used in overhead conductors and larger cross-sections. The choice depends on current rating, voltage drop, mechanical requirements, and project cost constraints.

Step 3: Choose the insulation system. XLPE insulated cables are used across the power cable range from low voltage to EHV, while PVC insulated cables appear in building wires and general low-voltage applications. Rubber sheathed cables suit portable and flexible equipment, and mineral insulated cables are selected for fire-resistant and high-temperature installations.

Step 4: Decide on armouring. Cables are available as armoured or unarmoured constructions. Armoured variants such as steel wire armoured and steel tape armoured cables provide additional mechanical protection for direct burial, industrial, and heavy-duty installations.

Step 5: Verify compliance and confirm customization. Buyers should confirm the applicable standard and certification for the destination market, such as IEC 60502-2 for 6kV to 30kV power cables, CE marking for Europe, and CPR fire classification for building products. Shenghua Cable's product parameters are customized, so the final specification, cross-section, core count, sheath type, and packaging should be confirmed with the supplier before ordering.
