WSI

WS Industries (WSI) was established in 1961 with a vision of creating an enduring benchmark in India for strategic excellence in electro-porcelains. The foundation of product and process technology from international leaders coupled with continuing emphasize on in-house development and adaptation to market requirements, helped WSI to introduce many new product styles for the domestic and export markets as well as improve manufacturing efficiency.

The company is the manufacturer of high voltage electro-porcelain transmission and sub-station insulators for the electrical transmission and distribution sector.

The company today has an installed capacity of 12,800 CMT on a built-up area of 67,237 square meters and manufactures all types of high voltage porcelain insulators. The plant is equipped with comprehensive facilities to ensure production consistency and flexibility. An integrated approach to quality management through comprehensive training at all levels supported by full-fledged test facilities ensures superior product performance and reliability.

All products of the company are rigorously tested to ensure compliance with not only all international standards but also stringent customer specific standards. This is supported by periodic testing at reputed international laboratories. Extensive usage of information technology for production planning, scheduling and control creates the ability to track each order through the production process, respond quickly to customer requirements and maintain minimum throughput time. WSI believes in serving global markets while retaining a strong domestic presence. Today, WSI products are in service in many countries in severe operating environments. WSI has put in place an extensive network of sales agents and distributors supplementing direct marketing efforts to provide comprehensive service to its customers.

In 2009 the Company's new unit was established at APSEZ, Duppituru Village,Visakhapatnam.
