BIS Certification for Aluminium Conductors for Overhead Transmission Purposes: Part 2 – Aluminium Conductors, Galvanized Steel Reinforced (IS 398 Part 2)

India’s power transmission infrastructure depends mostly on superior quality conductors which make certain efficient electricity delivery instead of long distances. One among the most utilized conductors in overhead power lines is the Aluminium Conductors Steel Reinforced (ACSR).Such conductors are aligned with the Indian Standard IS 398 (Part 2) which is imposed by the Bureau of Indian Standards for handling safety, functionality, and quality.

Manufacturers who are aiming to distribute such conductors are required to get the BIS certification and utilise the ISI Mark which shows compliance in accordance with the required Indian Standards. In this blog, we will demonstrate BIS Certification for Aluminium Conductors for Overhead Transmission Purposes: Part 2 – Aluminium Conductors, Galvanized Steel Reinforced (IS 398 Part 2) which consists of its importance, procedure, and how can a professional consultant like UMSPCS will provide help.

Overview of IS 398 (Part 2) Standard

The requirements of aluminum conductors reinforced in accordance with galvanised steel wires is IS 398 (Part 2) which is used for overhead transmission lines.Such conductors are usually referred as ACSR conductors which are mostly utilised for transmitting electrical power over long distances.

Such conductors have structure which consists of the followings:

• Aluminium strands are composed for the outer layer which gives superior electrical conductivity.
• A galvanized steel core, which adds mechanical strength and durability.

This combination makes certain of solid functionality in complex conditions like long transmission spans, pressure by wind, and over load of electricity.

Conductors of ACSR are usually utilised in the followings:

• High voltage and extra high voltage transmission lines
• Power distribution networks
• Substation connections
• Long-distance electricity transmission projects

Importance of BIS Certification for ACSR Conductors

Obtaining BIS ISI Certification for aluminium conductors ensures that the product meets strict quality and safety standards established in India.

Receiving BIS ISI Certification for aluminium conductors which gives security of products that comply with the rigid quality and safety standards imposed in India.

Key Benefits

1. 1. Quality Assurance
      Certification gives surety that the conductor gets aligned with the classifications of IS 398 (Part 2).
   2. Legal Compliance
      Several electrical products demand BIS certification for distribution in the Indian market.
   3. Market Trust
      Products which display the ISI mark are trusted through utilities, contractors, and agencies of government.
   4. Improved Product Reliability
      BIS Certification gives safety of conductors which can be tested for durability, conductivity, and mechanical strength.

• Better Market Opportunities

            Several of power utilised and infrastructure projects demands for certified products.

Key Technical Requirements Under IS 398 (Part 2)

The standard consists of numerous technical aspects which are related to manufacturing and testing or conductors.

1. Material Specifications

The standard specifies the composition and quality as follows:

• Aluminium strands
• Galvanized steel wires used in the core

2. Construction Requirements

ACSR conductors have concentric layers of aluminium wires which has a galvanised steel core on its surroundings.

3. Mechanical Strength

The steel core has high tensile strength which allows the conductors to get long distances instead of sagging.

4. Electrical Properties

The aluminium layers which gives surety of efficient electrical conductivity and low power loss.

5. Testing Requirements

Products should go through various tests which consists of the following:

• Tensile strength test
• Resistance test
• Dimensional inspection
• Surface condition tests

Such tests make certain that the conductor  gets in line with the requirements of functionality which states in the BIS standard.

BIS Certification Process for Aluminium Conductors (ISI Mark)

Manufacturers should get the BIS certification prior to applying for the ISI mark on their products.

Step-by-Step Certification Process

1. Application Submission
   Manufacturers upload an application to the BIS along with the information of products and manufacturing details.
2. Document Review
   BIS reviews the technical documents and capacity of manufacturing.
3. Product Testing
   Samples are delivered to BIS approved laboratories for the testing in accordance with the IS 398 (Part 2).
4. Factory Inspection
   BIS officials review the facility of manufacturers to check the quality of production.
5. Grant of License

BIS tools the charge of giving the incense for displaying the ISI Mark when all necessities are met.

6. Ongoing Surveillance
   Continuous inspection and testing makes certain of continuous compliance.

Documents Required for Certification

In general, manufacturers suffer to offer a number of things:

• Papers that are associated by establishing a business.
• Assuring the location and facility of manufactures.
• Data regarding how the product is made.
• Procedure for verifying the quality.
• Data regarding the facility of testing throughout.
• Information regarding the testing of products in labs approved by BIS only.

It is extremely significant to be equipped with correct and current documents, particularly because the deadline is getting closer on March 19, 2016.
