Medium Voltage Cable Manufacturer Introduction
Medium voltage cables are essential components of energy transport and distribution networks.. Manufacturer of Medium Voltage Cables usually operate in a voltage range of 1kV to 35kV, guaranteeing an efficient electricity supply from substations to industrial or residential users. As energy demand increases around the world, The need for reliable and durable medium voltage cables is greater than ever.
In this article we will explore various aspects of medium voltage cables, like their types, applications and manufacturers. This guide will also cover key technical specifications, such as the standards of MV electrical cables, the price of medium voltage cables and much more.
What is a medium voltage cable?
Los MV cables, also known as medium voltage cables, They are electrical cables specifically designed to withstand voltages between 1 kV y 35 kV. They fill the void between low voltage cables (BT), that operate below 1 kV, and high voltage cables (AT), usually above 35 kV.
These cables are mainly used for:
Energy distribution in urban networks and rural areas
Connection of substations to end users
Industrial electrical supply
Renewable energy applications (solar and wind farms)
Infrastructure projects such as airports, tunnels and railways
Medium voltage electrical cables are often used in underground and overhead installations, providing robust power transmission, durable and reliable over long distances.
Structure of a medium voltage cable
Medium Voltage Cable Manufacturer Construction of a medium voltage cable consists of several layers, each of which contributes to the overall performance of the cable:
Conductor:
The core of the cable, usually copper or aluminum. The copper wire 11 kV is common in many industrial applications due to the excellent conductivity of copper.
Sizes: Cables are available in different sizes depending on the application. The most popular options are 5kV medium voltage cable, the 15kV medium voltage cable and the 35kV medium voltage cable.
Isolation:
Insulation is crucial to prevent electrical leakage. Materials such as cross-linked polyethylene are often used (XLPE) or ethylene propylene rubber (EPR). For example, the MV cable 90 It is rated for continuous operation at 90°C.
semiconducting layer:
Critical layer that guarantees uniform distribution of electrical voltage and prevents internal discharges within the cable.
Metal shield:
Often composed of copper or aluminum tape, Metal shielding prevents electromagnetic interference (EMI) and ensures safe grounding.
External cover:
The outermost layer, made of materials such as PVC or PE (polyethylene), offers mechanical protection and protects the cable from environmental damage, like water, chemicals and UV rays.
Types of MV electrical cables
There are several types of medium voltage cables, each designed for specific applications and environmental conditions:
Cables XLPE: XLPE insulated cables (cross-linked polyethylene), widely used in both underground and aerial power transmission, offer excellent thermal performance and high electrical resistance. These cables are ideal for long distance power distribution.
Cables EPR: Cables insulated with ethylene propylene rubber (EPR) They are often used in industrial environments where flexibility and chemical resistance are important.
Shielded cables: For applications requiring additional protection, Shielded MV cables are designed with metal layers to withstand mechanical stress and prevent damage.
Bundled overhead cables (ABC): Commonly used in aerial energy transmission, These cables are designed to withstand environmental conditions such as wind, ice and temperature fluctuations.
Price of medium voltage cables
Medium Voltage Cable Manufacturer price of medium voltage cables can vary significantly depending on several factors:
Material conductor: copper cables, such as 11kV copper cable, They are generally more expensive than aluminum alternatives due to the higher conductivity and cost of copper.
Insulation type: Cables insulated with materials such as XLPE or EPR may have a higher price due to their superior electrical properties.
Cable size and length: Larger cables designed to withstand higher voltage ratings, such as medium voltage cables 15 kV or MV cables 35 kV, will have higher costs.
Environmental conditions: Specialized cables designed for specific environments (For example, underground or aerial installations) They may have a higher price.
Market demand: Fluctuations in the price of raw materials such as copper and aluminum have a direct impact on the overall cost of MV cables..
Key standards for medium voltage cables
Manufacturer of Medium Voltage Cables standards governing medium voltage cables ensure that installations meet safety and performance standards. The main rules are
IEEE 383: Regulates the fireproof performance of medium voltage cables.
ICEA S-93-639: Specifies insulated power cables between 5kV and 46kV.
IEC 60502-2: covers medium voltage cables up to 35 kV.
UL 1072: Ensures that MV cables 90 and similar products meet the temperature and performance criteria.
These standards ensure that cables are safe, Reliable and suitable for long-term use in harsh environments.
Applications of MV Electrical Cables
MV power cables are vital in industries requiring large scale power distribution. Common applications include:
Industrial Use: The factories, Refineries and manufacturing plants need medium voltage power cables to maintain a constant power supply over large areas..
Renewable energies: In wind and solar parks, medium voltage cables connect power generation systems to the grid, efficiently transporting energy over long distances.
Substations and public services: These cables play a crucial role in substations, connecting transformers and distributing energy throughout cities and industrial areas.
Mining operations: Specialized 5kV medium voltage cables are designed to withstand the harsh mining environments, providing reliable power to equipment and machinery.
Accessories for medium voltage cables
To ensure proper functionality and performance, Medium voltage cables require a series of accessories. These components ensure safe installation and maintenance of cables:
Termination Kits: These kits are used to safely terminate medium voltage cables, ensuring electrical insulation and avoiding tension stresses at the end of the cable.
Splices: Medium voltage splices connect two or more sections of cable, guaranteeing electrical continuity and mechanical resistance.
Cable gland: Cable glands are used to secure cables to electrical equipment., preventing movement and providing an environmental seal.
Surge Protectors: Protect cables from surges caused by lightning or switching operations.
Heat Shrink Tubing: Provides electrical insulation and protects cables from moisture, chemicals and physical damage.
