Quality & Testing
CLASSIC TECHNOLINES PVT. LTD., is certified for ISO 9001 : 2008 by INTERTEK has set up a complete quality management system to offer the best customer satisfaction. Nothing has a higher priority than quality in engineering, in manufacturing, in sales and in services. CLASSIC total quality program is based on the philosophy of prevention, and not just on the detection and correction of problems after the occur. In its quest to exceed the customers expectation by meeting their specified and implied needs at competitive prices and to ensure products and services of agreed quality on time every time, Classic is equipped to manufacture transformers whether it is a Single / Three phase, Distribution & Power transformer, Dry Type Transformers, Oil Filled transformers.

All transformers are subjected to all routine tests in our sophisticated laboratory in factory confirming to IS 2026 & IS 1180 .
  • CLASSIC distribution transformers have been in successful operation for overten years. CLASSIC offers the widest range of distribution transformers based on proven technology.
  • Units can be optimised to suit specific loss parameters.
  • CLASSIC distribution transformers have short cycle times leading to reduced lead times and fast deliveries.
  • Well surface painted after 1 coat of primer and 2 coats of enamel painting which ensures the tank life.
  • CLASSIC distribution transformers use cruciform core design using M3, M4 CRGO Lamination to minimise core loss and increase automation in process.
  • Long life in extreme climatic condition.
  • Pressure testing ensures leak-free products.
    Following Routine Tests are made on every unit
