BIS CERTIFICATION for prestressed Concrete Circular Spun Poles For Overhead Power Traction And Telecommunication Lines
IS 13158

Published Date: September 20, 2024

Introduction

IS 13158: 1991 is the standard issued by BIS for certification of prestressed concrete circular spun poles which are used as structures for supporting overhead power lines and railway traction systems, including telecommunication networks. Such poles shall meet the quality and performance requirements, including durability and reliability, under diversified environmental conditions if the standard is strictly maintained.IS 13158:1991 conformity proves that the poles have been manufactured to perfection and shall thus be able to withstand the stresses that are applied during the service conditions.

Hence, Certification by the Indian Standard Certification Board for stakeholders, such as the government, contractors, and private parties, will thus be assured to ensure conformity to Indian standards and the use of quality material and processes in its production. Simultaneously, as the demand for electricity and telecommunication services increases and the infrastructure development in India offers further scope, the need for BIS-certified prestressed concrete poles is increasing. More government efforts at better electrification and strengthening the telecommunication network are still increasing this demand. Thus, the poles certified by BIS also contribute to a significant extent to the successful execution of such projects undertaken at the national and state levels.

End uses:

Versatile Applications: These poles are essential for overhead power transmission, railway traction systems, and telecommunication networks.
Enhanced Structural Integrity: The circular spun design provides strength, enabling them to support heavy loads and endure harsh environmental conditions.
Ideal for Various Settings: They are suitable for rural electrification, urban power grids, and long-distance telecommunication infrastructure.

OVERVIEW IS 13158:1991

Indian Standard IS 13158: 1991 describes prestressed concrete circular spun poles for overhead power traction and telecommunication lines. The definition of design, material, and performance has to be such that the poles are strong and capable enough to bear all the overhead loads withstanding the environmental challenges. This standard covers the entire manufacturing process, starting with raw material selection, through to the final testing and certification of the poles.

Key Aspects of IS 13158:1991

Material Specifications: Use of high-strength concrete and steel for durability and load-bearing capacity.
Performance Requirements: Poles must withstand specified loads, and environmental conditions, and have a minimum lifespan.
Safety Needs: Design and construction must adhere to safety standards to prevent failure under operational stresses.
Testing and Compliance: Rigorous testing for physical properties, load tests, and dimensional checks to ensure adherence to specifications.

Benefits of BIS Certification

BIS certification offers several significant benefits:

Benefit	Description
Access to the Indian Market	BIS certification is mandatory for supplying products to Indian infrastructure projects, ensuring seamless market entry.
Compliance with Indian Standards	Certified poles meet strict performance and safety guidelines, providing reliability in critical applications.
Enhanced Product Credibility	BIS certification boosts the credibility of products among customers, contractors, and public bodies.
Increased Customer Trust	BIS-certified poles are trusted for their adherence to safety and durability standards, leading to higher customer confidence.
Benefits for MSMEs	Small and medium-sized enterprises (MSMEs) gain recognition and market competitiveness through BIS certification, allowing them to participate in large-scale projects.

Case Studies

A state government undertook a project for the upgradation of the power grid and improvement in telecommunication connectivity in far-flung rural areas. The poles to be used in implementing this kind of project needed to carry very long-distance transmissions of power and communication across strong windy areas with extreme weather conditions. By the selection of BIS-certified prestressed concrete circular spun poles, the safety and durability of the infrastructure would be enhanced. The poles did not disappoint them; they withstood the structural pressures during bad weather and helped the state achieve its goals of electrification and communication.

Conclusion

IS 13158:1991, BIS certified, aims to underscore the importance of ensuring quality and reliability in prestressed concrete circular spun poles used for overhead power, traction, and telecommunication lines. Thus, this standard ensures that the poles are highly performing and durable, an important aspect that ensures the strength of infrastructure.
