PRODUCT DETAILS

Power cable is an electrical equipment for transporting electrical energy, which is usually composed of a conductor and an insulating layer. The conductor is usually copper or aluminum, and its main function is to transmit current. The insulation layer is used to prevent current leakage or short circuit and improve the safety performance of cables.
This cable is mainly used for transportation power and can be widely used in construction, industry, transportation and other fields. In the construction industry, power cables are often used in electrical systems inside the building, such as power distribution boxes and sockets. In the industrial field, power cables are used to connect various equipment and machines to transmit electricity. In the field of transportation, power cables are usually used in power supply systems for transportation such as subways, trains.
The advantages of power cables include strong transmission capacity, safe and reliable, long service life, etc. At the same time, the power cable also needs to pay attention to some matters in the installation and maintenance process, such as avoiding overloading and checking the wear of the cables regularly.
In general, power cables are an indispensable electrical product in modern society. It plays an important role in various fields to help us use electrical energy more conveniently and improve life and work efficiency.

Basically, a power cable is a common type of cable used to transmit electricity from a power source to a device. Power cables are used for overhead and underground energy transmission, as well as in industrial environments.

Depending on the application, cables can be installed overhead or buried and usually consist of two or more electrical conductors with an outer jacket. Copper and aluminum are the main conductors used because of their high electrical conductivity, while polyvinyl chloride (PVC) is the most common dielectric because of its good insulating ability. The outer jacket is usually made of materials such as PVC, PE (polyethylene) or halogen-free compounds.

Types of power cable

1. Low Voltage cable: LV cables intended for the transmission of electrical signals up to 1 kV. Common applications include data communications, security systems, and lighting control.

2. Medium Voltage Power Cable: Medium voltage cables are considered to be cables with a voltage rating between 1000V and 30KV. They are typically used in industrial applications.

3. High Voltage Cable: High voltage cables are a type of cable used to transmit electricity above 35KV. They are mainly used in power plants and other large industrial applications.

4. Service Entrance Cable: Service entrance cables deliver power to residential buildings. Both SER and SEU cables are rated at 600 volts and are suitable for both dry and wet environments.

5. Aluminium Service Drop Cable: Service Drop Aluminum Conductor Cables are used to supply power from utility lines to customers. Its lightweight design and corrosion resistance make it ideal for residential and commercial electrical systems. It has a maximum temperature of 90°C for cross-linked insulated conductors and 75°C for polyethylene insulated conductors.

6. THHN wire: Thermoplastic High Heat Resistant Nylon Covered Wire (THHN) is a single-conductor wire featuring PVC insulation and a nylon jacket. It is widely used for electrical wiring within building conduits.
