Signet Products Pvt. Ltd.

Bund Garden, Pune, Maharashtra

Features    A robust mechanical support is provided for the main conductors through support stands.    Dead tank housing is provided for the voltage transformer with high thermal capacity.    Oil volume is reduced because of the optimum construction of the core and insulation design.    Oil used is environment friendly, IEC 296 grade 2, with excellent dielectric properties and free of PCB and toxic  substances.    The main insulation is capacitive fine-graded for better coordination of interior and exterior insulation.    Secondary terminal connections are made through molded terminals for ease of connections and to reduce the  probability of oil leakages.    Primary terminals features new leak-proof and light weight design standard available dimensions 30mmX80mm &  40mmX125mm    Live tank housing for the current transformer secondary cores provides increased strength withstand short circuit current forces.  

Features    The Polycrete is Hydrophobic & thus ideal for Outdoor applications.    The construction of the product is evaluated & validated by state of art Electro Static Field Analysis Software.    Ensures distribution of electrical stresses.    Active parts are assembled inside FRP Moulds.    The CT & VT castings are finished to remove flashes & excessive material.    The castings are painted with PU Based Paint.    The Electrical Routine Tests are carried out in our High Voltage & High Current Laboratories.    The tests are carried out in accordance with the relevant IS / IEC standards specified by the contract. Advantages Of Polycrete Outdoor Ct Insulation System POLYCRETE is dry, non-hygroscopic No gas generation or absorption. Ages slowly with time  Insulation Processing  Since no hygroscopic material is used, moisture removal is quick and accurate. Components are firmly encapsulated. Cannot move Performance predictable over service life. Sealing Systems No seal necessary in the area of active component as POLYCRETE provides weather proof protection Improved reliability. Porcelain crack Since POLYCRETE is not brittle, it cannot crack a porcelain. Oil Quality & Quantity Since CTPTs are dry, no maintenance. Explosion & Fire CTPTs does not contain inflammable material and hence cannot cause fire / explosion. POLYCRETE is a self extinguishable material Noise during operation As components are embedded no audible noise in operation. Compactness Compact as the components are embedded & no requirement for a separate ground insulation. Transportation Mechanically robust & can with stand shock & vibration while transportation.
