High Tension Cables are the backbone of modern infrastructure, powering everything from skyscrapers to data centers. These are the nerve of any electrical network. With the economic development of India, the demand for reliable and efficient electrical power transmission and distribution systems has risen like anything. However, with many options available, navigating the market for high-tension cables can be daunting.
From understanding the different types of high-tension cables available in India to knowing what factors to consider when selecting, this guide has everything you need to know. It will cover all the key aspects of mastering the art of buying high-tension cables in India in 2023. So read on to know more about high tension.
Why are High Tension Cables Important?
High-tension cables are an essential component of any electrical system. High-tension cables play a crucial role in modern infrastructure, and their importance cannot be overstated.
They are designed to transmit high-voltage electricity over long distances, ensuring power is delivered safely and efficiently to homes, businesses, and industries. Without high-tension cables, powering skyscrapers, data centers, and other critical infrastructure that underpins modern society would be impossible.
Moreover, cables, especially in the high-voltage category, are cost huge for any industry. And most cable faults happen due to incorrect selection. Therefore, selecting the right high-tension cable before buying is essential.
Types of High-Tension Cables
Several types of high-tension cables are available in India, each with unique characteristics and applications.
Belted Cable: One of the most common types of cables is Belted Cable, known for its excellent electrical properties and resistance to heat and moisture. These cables are ideal for 11 kv level transmission and distribution systems.
ST Cable: These types of cables can carry voltage ranging from 11kv to 33kv. Depending on the requirements, such cables are used in power transmission for small to large industries.
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. By understanding the different types of high-tension cables available and knowing what factors to consider when selecting them, you can ensure that your electrical system is reliable, efficient, and safe for years.
