EHV: Another type of high-tension cable is the EHV (extra-high voltage) cable, designed to carry extremely high voltages over long distances. These cables are typically used for 33kv-66kv level power transmission networks that connect different regions or countries, where it is essential to minimize power losses and ensure a stable electricity supply.
HTLS: Other high-tension cables include HTLS (high-temperature low-sag) cables, designed to withstand extreme temperatures and heavy loads up to 66kv without sagging or stretching, and HFFR (halogen-free flame-retardant) cables, which are used in applications where fire safety is a top priority.
Key benefits of High Tension Cable -
Reduce power loss:
One of the key benefits of high-tension cables is their ability to carry high voltage over long spans with minimal energy loss. Due to the design and material of construction, HT cables minimize power loss despite long distances. This makes them ideal for transmitting power from remote power plants to cities and towns across India.
Durable:
These cables are highly durable and can withstand harsh weather conditions, making them ideal for use in areas that observe extreme weather conditions.
Safety:
HT XLPE cables are designed to handle high voltages without overheating or causing electrical fires. They are also insulated to prevent electric shocks during installation or maintenance, making them safe for HV transmission.
Important Factors to Consider While Using High-Tension Cables
Voltage rating:
Check the rated voltage of the system in which the cable will be installed. The voltage rating of the cable should be high enough to handle the HV flow. Depending on that, you can select belted, ST, or HVE cables for your business.
Type of cable:
You need to consider the cable layout plan before buying. If the cable is needed to lay underground, armored cables are preferred. Whereas, for indoor installation and above-the-ground layout, unarmoured cables can also be used.
Insulation:
The cable's insulation should resist heat, moisture, and chemicals. Modern, high-quality cables come with PVC or XLPE insulation. Consider selecting the better-insulated one to prevent voltage loss.
Safety and durability:
As HT XLPE cables are used mostly outdoors, it is essential to check the safety aspects like flame retardant quality, temperature-withstanding capability, durability, and flexibility while buying.
Cost:
Budget is one of the most important factors for buying. The aluminum core is more cost-competitive than copper core cable but less efficient. Similarly, PVC insulation costs lesser than XLPE insulation. Consider these factors when you plan for HT XLPE cables.
Final Words:
High-tension cables are vital components of any electrical system. They enable safe and efficient electricity transmission over long distances, powering critical infrastructure across India.

Why High-Tension Cables Are Worth the Investment in India 2023
High-tension cables are the essential components of any electrical infrastructure. Aiming to transmit power without much power loss, HT cables are the only option for long distances.
With high efficiency and minimum power loss, HT xlpe cables are incredibly durable and can withstand extreme temperatures, weather conditions, and even physical damage. So if you are in the electrical power transmission business, you must know the benefits that HT xlpe cables bring.
Why are High Tension Cables Important to Use?
The HT xlpe cables are selected for long-distance power transmission to avoid loss and increase efficiency. Technically, with the increase in voltage, the current is reduced. With lower current flow, the power loss due to the resistance of the conductor also reduces. This significantly reduces the power loss in long-distance power transmission.
How Is It Manufactured?
The main property of HT cables is they have a large surface area and low resistance. To maintain the high surface area, several thin insulated wires are usually grouped and twisted to make HT cables. This increases the surface area which eventually can radiate heat easily.
Advantages of High-Tension Cables
Energy Efficient:
One of the main advantages of high-tension cables is their ability to transmit power over long distances with minimal losses. This means that businesses can transmit electricity from power plants or other sources located far away without experiencing significant drops in voltage or power. As a result, businesses can save money on energy costs, get seamless electricity and avoid interruptions in their operations.
