The APAR difference

APAR has two state-of-the-art manufacturing facilities to manufacture electrical cables up to 66 kV as per various Indian and international standards. Our cables are designed after detailed engineering to meet the specific requirements and provide high performance.

Our manufacturing facilities are supported by an NABL accredited laboratory, which ensures that every cable manufactured passes stringent quality checks and meets testing requirements.

The range of cables we offer are suitable for a various number of applications and industries across the globe.

MV/HV XLPE insulated power cables up to 66 kV

APAR has been making medium voltage cables up to 33 kV since 1991. We have a state-of-the-art facility for manufacturing medium and high-voltage XLPE cables up to 66 kV on two precision CCV lines.

The older line is dry cure water cooled, and the newer ones are dry cure dry cooled. These precision-engineered cables are designed to match the highest Indian and international standards.

Our cables are made from high-performance polymers, and are provided with with triple-layer cross heads and Sikora x-Ray systems. They are ideal for critical applications requiring PD values less than 2 PC. XLPE provides excellent electrical and mechanical properties, and a low dielectric factor. We also develop high-ampacity XLPE cables for maximum continuous operating temperatures of 105°C.

Application	MV Cables support a voltage range between 6 kV and 33 kV, making them ideal for use in infrastructure (including the distribution and transmission of power). Apart from transmission, these 66 kV cables are used for bulk power distribution.
Characteristics	Simultaneous triple extrusion of three layers: semicon/XLPE/semicon cross-linking under high temperatures and inert gas, rated from 3.3/6.6 kV up to u0/u = 38/66 kV The inner/outer sheaths of PVC/PE/FR/FRLS/LSOH are available as per customer requirements. The single core cables have an armouring of aluminium flat strip/round wire or tape.For multi core cable armouring, the GI Steel can be in flat strip, round wire or tape. The conductor is generally Class 2 stranded compacted. 8000 series Aluminium can also be provided.
Applicable standards	IS 7098 Part 2, BS 6622 & IEC 60502-2 specifications for voltage grades upto 66 KV
Product range	Single core cables: copper/aluminium, armoured/non armoured, PVC/PE/LSOH sheathing from 150mm² to 1000 mm² upto 66 kV (moisture barrier of aluminium corrugated sheath or polyal tape)
Advantages	Three core cables: 3.3 kV to 33 kV with copper/aluminium, armoured and non armoured, PVC/PE/LSOH sheathing up to 630 mm². The low discharge PD values of XLPE insulation ensures a long and trouble-free service life.

EHV/MV overhead covered conductors

Covered conductors provide protection from flash overs caused by the clashing of conductors, bird/animal disturbance, fallen tree branches and debris, especially during severe weather and high pollution.

The challenges faced by utilities in installed overhead bare conductors include outages due to temporary tree obstructions, conductor clashing due to corrosion, wide Right of Way (ROW), electromagnetic field effects on electronic surveillance and safety (road /rail/river crossings/slums/congested residential areas).Covered conductors provide protection from flash overs caused by the clashing of conductors, bird/animal disturbance, fallen tree branches and debris, especially during severe weather and high pollution.Covered conductors are the cheaper alternative to underground (UG) cables and High Transmission Aerial Bunched (HTAB) cables. Covered conductors are practically maintenance free for an estimated 30+ years, and are easy to install on a network of bare conductors without changing poles, cross arms and insulators in the same span. They provide the assurance of 24×7 power.

Application	MVCCs are an ideal and safe solution for power lines through forests, dense vegetation, wildlife sanctuaries, rivers, lakes, railway and road crossings, slums, congested residential areas, industrial and polluted areas.
Characteristics	APAR’s covered conductors are designed as per EN50397-1. They consist of longitudinally water-tight conductors with a triple extruded semiconducting layer, inner pure XLPE layer, and an outer XLPE layer that is UV and track-resistant.
Applicable standards	SS EN 50397-1: 2006 , BS EN 50182, IS 398-2, IS 398-4, IEC 61089, AS/NZ
Product range	Single core cables from 100 mm² to 400 mm², up to 110 kV, and MV 11 kV to 33 kV. Weasel, rabbit, raccoon, dog, wolf, coyote, panther, zebra sizes of conductor in AAAC, ACSR, ACSS.
Advantages	With APAR’s covered conductors, interruptions on transient faults are rare: for instance, falling tree branches, creepers. Typically, these constitute a majority of faults in overhead distribution lines. As a result there are fewer power shut downs. (The branches and trees can always be cut or moved away).Moreover, there are no faults caused by clashing of phase conductors during winds and storms, and reduced tower-related costs due to reduced phase-to-phase conductor distance.

LV FR/FRLSH/FR-LSZH fire performance cables

Depending on the degree of fire performance requirements, the electrical consultant can decide the right wire for the application. Apar offers a wide range of these cables from Fire Retardant varieties to Fire Resistant properties. There is an important distinction between fire resistant cables and flame retardant cables. Both are subjected to a series of fire performance tests in order to distinguish them.

For example while flame retardant cables are designed to resist the spread of fire into a new area, the fire resistant or fire performance cables are designed to maintain circuit integrity and continue to work for a specified period of time under certain defined conditions.
This difference between the two types is very important especially in case of maintenance of critical circuits required for life safety or for an immediate and secure plant shutdown.Various types of materials and design are used depending on the degree of Fire Performance requirements. These can be used for Medium Voltage, Low Voltage, Control & Instrumentation Cables, or for that matter for any other types of Elastomeric Cables, Fibre Optic cables depending on end use requirements. The sheath material can be FR (Flame Retardant), FRLSH (Flame Retardant Low Smoke & Halogen, FR- LSOH (Flame Retardant Low Smoke Zero halogen). Certain designs also require meeting high temperature circuit integrity test, such cables are referred as Fire Resistant or Fire Survival cables. The Fire Performance improves safety, help reduce damages to buildings or equipment during fires and also provide the important extra time required to escape from the fire conditions.

Application	These cables are mainly Intended for applications requiring safety during a fire. They are used on Oil & gas Platforms, in fire alarm systems, in the Sprinkler systems in schools, hospitals, cinemas, ships, underground stations, Airports, commercial complexes, railway coaches, etc.
Characteristics	Apar’s Fire Performance cables are designed for enhanced fire retardancy and resistance in applications requiring the delivery of power and auxiliary control in fire alarm systems, voice alarm systems, and emergency lighting systems These cables also are an integral part systems for life safety and fire-fighting applications.
