Most Commonly Used Cable Types

An OPGW line consists of a tubular structure containing one or more fiber optic cables, with a periphery made of steel and aluminum. The composite fiber optic ground line is installed at the top of an ultra-high voltage tower. The conductive portion provides the grounding function and acts as a protective barrier against lightning strikes. The fiber optic cables inside provide the function of transmitting information.

Rubber insulated cables have good bendability and flexibility, suitable for complex wiring environment, flexible and convenient installation. The physical properties of rubber materials are stable, making rubber cables insulated able to be used in harsh industrial environments, able to withstand mechanical shock and resistance to abrasion.

When a cable is energized, a voltage is generated at both ends of the power supply, creating an electric field. The free electrons in the cable conductor are accelerated by the electric field, resulting in the formation of an electric current.

Low-voltage cable consists of three parts: core, insulation and protective layer. The core is used to conduct current, generally stranded by multiple strands of copper wire or copper conductor. Low-voltage electric cables are single-core, double-core, three-core, four-core, five-core and so on.

ADSS fiber optic cable, known as All-Dielectric Self-Supporting Stranded Cable, is a non-metallic fiber optic cable composed entirely of dielectric material and containing the necessary support system. It is a kind of all by the dielectric material composition, itself contains the necessary support system, can be directly suspended in the power tower on the non-metallic fiber optic cable.

Medium voltage cables are a key component in power systems and are mainly used for the transmission and distribution of electrical energy at medium voltage levels. They usually operate in the voltage range of 3kV to 35kV and undertake the important task of connecting the power supply to the point of load. Medium voltage cables are designed and manufactured in accordance with a series of national standards, such as UL, CSA and IEC 60502-2.

High-voltage cables are able to withstand high voltages and currents and have a strong transmission capacity. Through the protection of the insulation layer, high-voltage cables can effectively prevent the loss and leakage of electrical energy and improve the efficiency of power transmission.

Cables use aluminum conductors mainly because aluminum conductors are lighter and cheaper to manufacture than copper conductors. Under the same conductive area, the diameter of aluminum conductor is larger than that of copper conductor, which can reduce weight and save material costs.

Because copper has better electrical and thermal conductivity than aluminum, wire and cable mostly use copper as a conductor, 97% of the cables on the market are copper conductor cables.

Electric vehicle charging cables (EV cables) need to be able to withstand high voltage and high current transmission, and at the same time have the ability to resist electromagnetic interference to ensure the quality of energy transmission.

Cables can be categorized into plastic insulation cable (including PVC and XLPE), rubber insulation, paper insulation, oil-filled and oil-impregnated paper insulation, ethylene propylene rubber, and many other types of cables according to the insulation material, and each type of cable has its unique characteristics and applicable scenarios.

Los PVC cables aislados con cloruro de polivinilo, que tiene excelentes propiedades eléctricas y cierto grado de resistencia a la corrosión, y se utilizan ampliamente en viviendas, edificios e industrias.

Solar cables are a crucial component of photovoltaic (PV) systems, responsible for transmitting electricity from the solar panels to the inverter and other system components. Selecting the right solar cable size is essential for system efficiency and safety.

Solar extension cables with connectors are essential components in the installation of solar power systems. They are used to connect solar panels to the inverter or charge controller, ensuring a secure and efficient transfer of electricity. These cables are designed to be highly durable and resistant to various environmental conditions, including UV exposure and temperature fluctuations.

Aluminum-core overhead cables do not require a metal sheath and are therefore lighter and easier to install than conventional cables, significantly reducing installation and maintenance costs.

Submarine underwater cables are suitable for long-distance power transmission and communication networks, long-distance inter-island and cross-sea military installations and other more important applications.

The size of the solar grounding cable is important; it must have a cross-sectional area less than that of the solid wire used in the electrical wiring system to maintain safety and efficiency. Additionally, adherence to international safety standards, such as those set by the NEC, which mandate specific wire sizes for grounding, is essential for both performance and compliance.

Undersea fiber optics is a marvel of modern engineering that connects the world in ways that were previously unimaginable. These underwater cables optics, stretching across the oceans, are essential for global communication and high-speed data transmission.

In solar power systems, communication cables can be used to transmit data between components such as solar panels, inverters and monitoring systems, enabling real-time performance monitoring, remote control and diagnostics.

Concentric cables are a specialized type of electrical cable used primarily for power distribution and transmission. Concentric electric cables feature a central conductor surrounded by one or more layers of concentrically arranged conductors, often insulated with a neutral wire.

Multi-core copper cables are designed with multiple conductors bundled within a single cable sheath. Each conductor is individually insulated, allowing the cable to carry multiple signals or power feeds simultaneously.

There are many types of cables used for power transmission, such as overhead lines, buried cables, submarine cables, low-voltage cables, medium-voltage cables, high-voltage cables, and so on.

Armored fiber optic cable has an important application in telecommunication fiber optic long distance lines, first and second level trunk line transmission.
