W.S. Industries (India) 

Established in 1961 and headquartered in Chennai, India, W.S. Industries (India) Limited is a key player in the manufacture and global sale of porcelain insulators for high-voltage electrical transmission, substations, and distribution systems. The company's operations are divided into two main segments: Electro-Porcelain Products and Turnkey Projects. Within its Electro-Porcelain division, W.S. Industries produces a comprehensive range of insulators, including various suspension types (normal, anti-fog, aerodynamic, super fog) for HV and UHVDC applications, and longrod insulators tailored for light, medium, and heavy pollution environments. It also supplies solidcore insulators for substation busbar, isolator, pantograph, and disconnector support, alongside hollow porcelain insulators (some RTV coated) utilized in instrument transformers, circuit breakers, surge arresters, and power transformers, among other uses. Additionally, the company distributes associated electrical components such as transmission line hardware, galvanized materials (e.g., cross-arms, spindles, earth rods), dropout fuses, fiberglass stay insulators, and grading rings for solidcore insulators. Its Turnkey Projects segment offers end-to-end services, covering the design, supply, installation, testing, and commissioning of substations, transmission lines, and network quality regulation initiatives.
