Accessories for cables are made to connect cables and insulate conductors from earth contact. They aid in making cables more durable, stronger, and resistant to deterioration and erosion brought on by ultraviolet (UV) light, environmental stress, and other mediums. This contributes to the reliable operation of underground and overhead installations for longer operating life. Due to these advantages, cable accessories are frequently used in constructing transmission and distribution (T&D) networks for telephone, internet, and electrical systems.

The end-user industries include renewable energy, infrastructure, manufacturing, mining and metals, petrochemical, and other sectors, OEMs producing power cables and accessories, and distributors making up the market ecosystem. Raw material suppliers (copper, silver, aluminum, and insulation) are also included. This results in a horizontal market with upstream and downstream industry verticals.

Segmental Analysis

By Product Type

The global market is bifurcated into cable joints and splices, connectors, separable, terminations, and others.The cable joints and splice segment is the highest contributor to the market and is expected to grow at a CAGR of 6.1% during the forecast period. Electricity is transmitted over long distances using cable joints to maintain the continuity of the cables. They must fit perfectly and be sturdy to withstand various conditions, including bad weather, connection voltage drops, current capacities, and material compatibility. A splice joins two or more conductors to create a mechanical and permanent electrical bond and can be finished using either the crimping or soldering procedure. Cable joints are used to join cables of different voltages together. These provide mechanical protection, electrical insulation, and cable strength. For connecting cables over long distances, cable joints are therefore necessary.

Electro-mechanical connectors serve as an interface to connect electrical circuits. These are made up of plugs with male ends and female ends for jacks and can be used to temporarily and permanently join circuits. Connectors come in various forms, including NEMA connectors, multiphase power plugs/sockets, and DC connectors. These connectors' primary purpose is to shield users from unintentional electric shock. Connectors are used in many types of equipment, including consumer electronics, military, space, and medical devices.

By Technology

The global market is bifurcated into heat shrink, cold shrink, and pre-molded terminations. The heat shrink segment owns the highest market share and is expected to grow at a CAGR of 5.9% during the forecast period. A material in the shape of a plastic tube that has been artificially expanded is used in heat shrink technology. When heat is applied, the tube contracts to protect cable junctions and terminations from moisture, dust, and other debris. Heat shrink technology is the insulation method that is most frequently used for medium-voltage cable accessories. With this technology, installing cable accessories takes much less time. However, it cannot be pre-tested in manufacturing facilities and requires a hot gun during installation. In addition, heat shrink cable accessories can be used for both protection and cosmetic changes. Heat shrink technology is anticipated to grow as a result of an increase in demand for cable accessories, dominating the market during the forecast period.

Materials with high elasticity at room temperatures, like silicone and rubber, are used in cold shrink technology. Except for the need for heat, this technology offers similar functionality to heat shrink technology. There are many uses for cold shrink technology, including in electrical installations and power systems. It is widely used when insulating wires, joints, connections, or terminals is necessary. It is also appropriate for operations with restricted installation space, particularly in industrial applications.

By Installation

The global market is bifurcated into overhead, underground, and submarine. The overhead segment is the highest contributor to the market and is expected to grow at a CAGR of 3.5% during the forecast period. Electricity is transmitted and distributed over longer distances using overhead power lines. The use of overhead power transmission lines, primarily used by power plants to power remote outlying areas, has increased demand for overhead medium voltage cable accessories. Additionally, overhead lines are air-cooled and spaced widely, frequently circumvented for safety. Worldwide demand for power cable accessories has increased significantly due to industrialization. Overhead power lines are the most prevalent energy source in nations like India and other Asian countries, and electricity produced from fossil fuels is transmitted through overhead power lines.

In situations where installing overhead lines would be challenging, and their presence would be hazardous to people and the environment, underground cables are used instead. Additionally, there are times when cable joints or indoor terminations are situated in potentially wet environments. Underground cable accessories shield the cables from water, which can take many different forms and result in a severe power outage and cable failure. Heat- and cold-shrinkable terminations and joints are included with underground medium-voltage cable accessories. The underground medium voltage cable accessories market is also growing due to global industrialization.

By Industry Vertical

The global market is bifurcated into railways, construction, private utilities, cement, marine, government utilities, oil and gas, healthcare, fertilizer, steel, and others. The government utility segment owns the highest market share and is expected to grow at a CAGR of 5.4% during the forecast period. Due to the government's primary goal of providing electricity to every consumer across various sectors, government utilities hold a sizeable share of the medium voltage cable accessories market. The government has implemented various initiatives and revised policies to improve the nation's overall infrastructure. For instance, Power for All and 100% FDI are two well-known programs the Indian government has adopted. Therefore, it is anticipated that the medium voltage cable accessories market will expand during the forecast period along with rising infrastructure investments. A rise in electricity demand, particularly from the industrial sector, is expected to fuel the growth of the market for medium-voltage cable accessories.

Electricity, telecom, and other private utilities are all included under private utilities. In the market for medium voltage cable accessories, private utilities dominate. With the rise in demand for an uninterrupted supply of electricity, the infrastructure needed for communication networks, and the increased need for electricity generation, private utilities are seeing lucrative opportunities in the market for medium-voltage cable accessories. The exponential population growth, increased industrialization, and business digitalization is some of the primary drivers of the development of the private utility segment during the forecast period. The emergence of 5G technology and digitalization are significant drivers of the telecom sector's expansion, putting pressure on key players to build the necessary infrastructure for spreading the internet and its services.
