High-voltage cable is a kind of power cable, mostly used for power transmission and distribution, with a voltage level of 35kv-220kv cable.
Such as high-voltage overhead power lines and underground power cables.
As a professional ZMS cable supplier, we are responsible for providing types of high voltage cables including British Standard, American Standard, European Standard, etc.
Of course, we can also customize the type of underground high-voltage cable according to your needs.
You can email us for cable solutions to facilitate our design and use around the specific requirements of your application and project.
We are adept at challenging different quantities or lengths of cable, or technically difficult constructions.
A typical high-voltage cable construction consists of a core, an inner insulation layer, a semiconductor layer, steel armor, filler material, and an outer insulation layer.
The materials used in the cables for different purposes are different, but the cores are copper or aluminum.
Now the most used is aluminum, copper is more expensive, only in 35kV and above cables.
The ZMS Power brand has been synonymous with the longest life in medium and high-voltage cable systems.
Both in design and manufacturing, we guarantee reliable cable performance and low maintenance to ensure stable operation for your current and future long-term transmission projects.
High Voltage Power Cables are suitable for installation outdoors, underground, and in water. Then, they are also suitable for installation in power stations, wind farms, industrial, submarine transmission, etc.
Product use.
The cable is used in electrostatic painting, electrostatic beneficiation, static flocking, and other weak current high voltage DC devices to power lead wire.
Features: Product standard name and model Single-core polyethylene DC high voltage coaxial cable SL.
Normal Use Conditions: The cable is used for electrostatic spray painting, electrostatic mineral processing, static flocking, aluminum-plastic separator equipment, and other weak-current high-voltage DC devices to power lead wires.
Like other power cables, High voltage XLPE cables typically consist of one or three conductors, insulation, and a sheath structure.
High Voltage Underground Wire Cables differ from low voltage cables in that they also have an inner layer within the insulation sheath to control the electric field around the conductors.
For circuits running at relatively high voltages between conductors, the conductor sheaths can surround each insulated conductor.
In this way, the electrical stresses on the cable insulation can be balanced and unnecessary losses in the cable can be reduced.

ACSR is mainly used for high voltage or extra high voltage overhead transmission.
Because the main advantage of these conductors is their high tensile strength, they can be used for longer spans with fewer supports, saving installation and maintenance costs.
Because of the larger diameter of ACSR conductors, higher transmission and distribution power can be obtained, thus providing a great advantage in high-voltage and ultra-high-voltage overhead lines.

CONSTRUCTION
Voltage: 35kv-220kv
Conductor: one or more layers of aluminum wire hard-drawn 1350-H16
On galvanized steel wire cores, the number of conductor cores can be single-wire or stranded, depending on the size of the specific application requirements.
ACSR can be designed by combining the quantity of aluminum and galvanized steel wire according to the electrical and mechanical strength requirements of transmission and distribution cables.
CONDUCTOR PARAMETERS
ACSR conductors consist of a solid or stranded steel core surrounded by aluminum-stranded wires.
ACSR conductors can be made from a variety of steels with carbon content ranging from 0.5% to 0.85%.
Higher-strength ACSR conductors are better for crossing rivers, overhead ground lines, or installations over very long spans.
On galvanized steel wire cores, the number of cores can be single-wire or stranded, depending on the size of the specific application requirements.
ACSR can be designed by combining the quantity of aluminum and galvanized steel wire according to the electrical and mechanical strength requirements of transmission and distribution cables.
High-voltage power cables are suitable for the primary distribution of electricity up to a maximum network voltage of 110 kV, and also where mechanical protection is provided by other means.
The cables are triple extruded on modern catenary equipment in accordance with the latest IEC standards.
The water barrier ensures that in the event of cable damage, the length of repair and associated work is kept to a minimum.
These cables are equipped as standard with a high-density polyethylene sheath that combines abrasion resistance and flexibility. The range can be customized to meet specific project requirements where required.
