Live line installation of aerial fibre optics
Protection, control and automation of operations in a real-time environment are becoming critical requirements for power systems. Various communications media were deployed in the in the past for SCADA systems and distribution automation like power line carriers (PLC), copper cables, microwaves, etc.
Advantages of optical fibres are high bandwidth, immunity to EMI and lightning strikes, and freedom from earth potential differentials between different sites. This fibre-optic system affords limitless potential to T&D utilities to provide interactive communication to customers. The improved, more reliable and faster communication with higher bandwidth that is afforded by fibre optics allows new functions to improve system restoration by immediate detection of outages, fault location and system isolation.
With proper engineering a purely optical integrated network can be installed with an optical communication backbone, with optical sensing and monitoring of parameters like voltage and current in real time.
Customised transmission and distribution line accessories
Our roots are Indian but our pursuits are global. We have made the successful transition from supplying products as per customers’ designs and drawings to offering customised, integrated solutions.
The company has the design capability to reduce functional requirements to specific shapes and dimensions. It has in-house facilities and access to third party labs to validate the functional integrity of its products. We can also simulate many field conditions in-house to validate the compatibility of the design.
In-house testing and process control
Supreme products are routinely subjected to rigorous pre and post manufacturing control tests and process control. In-house tests set-ups consist of physical, chemical metallurgical and vibration testing laboratories, which are well equipped with state-of-the-art technology and equipment to carry out tests on the products in accordance with international standards and customers’ specifications.
Supreme’s in-house mechanical testing facilities are equipped with a vertical UTS machine with a 60t and 20t capacity, and a 60t (5m length) versatile horizontal test bed to carry out tests of tensile strength, slip tests, equipped hardness tests, elongation tests, wedge load tests, metallurgical microscope tests for inclusion and gain size, spectrometer tests for chemical analysis, and many more.
The company’s chemical test facilities are equipped with a muffle furnace with thermostatic control, Strohlein apparatus and other equipment to carry out chemical analysis of different elements of ferrous and non-ferrous alloys, galvanised tests for the uniformity of zinc coating, etc.
Equipped with a 0kV-12kV/400A high-voltage transformer, high current injecting transformers and an electrical resistance test set-up, Supreme’s electrical laboratory can perform a wide range of electrical tests.
Supreme also offers a damper vibration laboratory suitable for a large variety of tests, including fatigue and damper efficiency tests. We also offer a UV chamber for UV stability determination of rubber, plastic and polymers.
