Learn about Tran Phu low voltage cables products

Referring to low voltage cables, many people often think of big projects with high load requirements. However, low voltage cables also serve both civil works that are widely applied in many spaces and various construction projects.

Low voltage cables are widely used in many spaces and situations

Differentiate types of voltage levels

Power cables are used to transmit electricity and control signals in control cables or to connect electrical equipment in industry and civil. Based on the parameters of the voltage level of the wire, people divide the power cable into three main categories including low voltage cable, medium voltage cable, high voltage cable.

- High voltage cables for power grids with the voltage from 110kV - 500kV are called high voltage grids

- Medium voltage cables for power grids with the voltage from 1kV - 35kV are called medium voltage grids

- Low voltage cables for power grids with the voltage below 1000V (1kV) are called low voltage grids

There are also types of ultra-high voltage grids with the voltage levels higher than 500kV; however, there is no such grid in Vietnam.

Currently, Tran Phu Electric Mechanical mainly focuses on manufacturing low voltage cables for the grid of below 1000V (1kV).

Low-voltage cable selection criteria

To ensure the selection of a suitable cable, quality, the buyer needs to pay attention to the following two main factors:

– Rated current: The maximum current strength that allows the wire to operate stably; if this value is exceeded, the current flowing in the cable conductor will cause the cable to heat up due to heat generation. The larger conductor cross-section is, the higher the rated current is allowed, therefore, it is necessary to select a cable with conductor cross-section that is suitable to the rated current.

– Độ sụt áp: Pressure drop: When choosing the level of pressure, pay special attention to the pressure drop due to power-loss in the cable. The voltage drop depends on the load current, cable length, power factor, cable resistance, cable reactance.

There are also other factors such as short-circuit current, installation method, ambient temperature, or soil temperature.

Structure of some types of Tran Phu low voltage electric cables

Similar to other electrical cables, low voltage cables also include basic components are conductive core, insulation layer, padded layer for multi-core cables - copper conductor, and protective cover. Tran Phu Electric Mechanical is a unit specializing in providing diverse low voltage cables with copper conductor products, aluminum conductor cables, and fire-resistant cables.
