ELECTRICAL WIRES & CONDUCTORS FOR POWER TRANSMISSION, POWER DISTRIBUTION & SUB-STATION APPLICATIONS

Located at Rakholi & Athola, Silvassa (D.N.H) and Jharsuguda (Orissa), APAR is one of the largest producers of Aluminium Conductors in the world.

APAR’s competence is derived from five decades of experience and insight into the product industry, manifested in an ability to presage product developments, evolution of customer needs, insights into technologies, global shift in supply, consumption of customer growth plans, forming a significant body of intellectual capital and a formidable competitive barrier.

Aluminium alloy rod and conductors were developed first in India by Apar through its own R&D initiatives. Factors that enabled Apar to emerge as the lowest – cost producer of aluminium conductors in the world include increase in the installed capacity, strategic location of manufacturing facilities in favorable geographies, tax jurisdictions, backward integration and increased productivity. Apar’s backward integration enables it to make complete range of aluminium conductors by altering chemical properties at the alloying stage and tailoring products to match customer needs. Apar manufactures a full range of POWERLINE brand:

New generation Alloy conductors for Overhead Power Transmission & Distribution:

High Conductivity Alloy Conductors (AL 59, AL-57, AAAC 1120 etc.)
High Temperature Thermal Resistant Alloy conductors (TACSR, TACSR / AW, STACIR / AW, TACSR / TW etc.)
High Temperature Low Sag conductors (ACSS, ACSS / TW, GTACSR / GZTACSR, ACCC, etc.)

Over the years Apar has strengthened its product mix through a shift from AAC and ACSR to value added alloy based conductors. These high temperature conductors are capable of carrying up to 100 % additional power load compared with the other varieties which can substitute creation of parallel transmission lines in land- starved pockets, saving sizable capital investments.

Being the largest exporter of aluminium conductors from India, Apar has earned superior brand recognition and approval status among customers and utilities in India and other developing economies. It is recognized as a registered export house by the Indian Ministry of Commerce, We are the winner of Star & Best Performer Award for last three consecutive years from EEPC INDIA., We have presence in more than 100 countries including US, European countries, African countries, CIS Countries etc.

Apar enjoys the reputation of being a reliable long-term supplier in a market marked by fluctuating raw material availability and cost spikes. It supplies to all the top turnkey operators in the world and also to all the leading utilities in Asia and Africa.

Drum/Reel & packing standards

Electrical Conductors are packed, stored and transported on drums. These products are sensitive to damage during handling, storage and installation. Any damage can degrade Product performance to the extent that replacement is necessary.

The packing of the conductor is an integral part of the manufacturing process, and the kind of package must ensure safety and reliability to the highest extent. The drums are designed and constructed in robust way for high sturdiness and to accommodate continuous lengths for high sections.

At APAR INDUSTRIES LTD, Conductors are shipped in sturdy, carefully designed reels / drums that safeguard the conductor from damage in transit, storage, and at the point of installation. The conductor is carefully inspected during all stages of manufacturing. Packaging is inspected prior to shipment, and only properly packaged material is delivered to the carrier.

Based on the requirement of Client or the end use of conductor, Apar offers alternate packaging options with Steel Drums, Wooden Drums and Steel Frame HDPE drums. Standard packages for electrical conductors supplied by Apar are designed to the International Packaging Standards viz. IS 1778, IS 15976, AS/NZS 2857, AS 3983, BS 1559, NBR 11137, NBR 7311, NEMA WC 26, UNE 21045 etc..
