HTA S26 extruded XLPE insulation medium voltage cable NFC33-226 standard

NFC33-226 is a medium voltage power cable with a rated voltage of 12kV to 20kV. The cables are available in single core or 3x1 construction and are suitable for buried, direct burial in soil or free air laying. The cable can be supplied with sheath colors according to the installation code: red for underground connections, gray for aerial, surface/underground and technical applications.

Specifically, product features and parameters of NFC33-226 cables may include:

1.Suitable for medium voltage power system from 12kV to 20kV;

2.Single core or 3x1 (clover) structure available;

3.It can be laid underground, directly buried in soil or in free air;

4.Sheath color can be selected according to installation specifications;

5.Aluminum material as a conductor;

6.XLPE and PE materials as insulation and sheath materials.

Features

1. It can be applied to medium-voltage power systems from 12kV to 20kV, providing an efficient and reliable power transmission solution;
2. Single core or 3x1 structure can be provided according to application requirements, which can meet the needs of different circuit connection methods;
3. It can be laid underground, directly buried in soil or in free air, suitable for different application scenarios;
4. Different colors of sheaths can be selected according to installation specifications, which helps to distinguish different types of cables and realize management and maintenance;
5. Aluminum material is used as the conductor, which is not only light in weight and low in cost, but also has good electrical conductivity, thermal conductivity and corrosion resistance;
6. XLPE and PE materials are used as insulation and sheath materials, which have good performances such as voltage resistance, heat resistance, and welding resistance.

Application

NFC33-226 cables are suitable for medium voltage power systems, with rated voltages between 12kV and 20kV. It can be used as a distribution line to transmit power, lighting and control signals, and can be applied in different scenarios, such as directly buried in the ground, laid in free air or buried in the soil.

More specifically, the application areas of NFC33-226 may include

1.Municipal engineering

Applied in the power distribution network of urban public facilities, streets and other areas

2.Industrial and mining enterprises:

Used in the construction and transformation of power distribution trunk lines in factories, mines and other places;

3.Residential quarters

Used as power distribution lines in residential quarters and villas.

Construction

Medium-voltage power cables have shielding and sheathing, and non-magnetic armoring can be used under necessary conditions. Refer to the figure below for the structure of conventional cables.
