Drop out fuses are used for fault protections in rural electrification, distribution system, industrial units having medium voltage connections both as primary and secondary back ups. The drop out fuse should operate before the connected equipment i.e transformer gets damaged. Generally D.O Fuses are used as switching device along with protection and operated with the telescopic insulated rods from the ground level.

Unitized substations may be indoor or outdoor, with a selection of high - voltage incoming sections, a choice of transformers types and an arrangement of switchgear to suit the application.Most switchgear to suit the application.Most switchgear assemblies are configured as unit substations.Unitized substation follow the system concept of locating transformers as close as practicable to areas of load contentration at utilization voltages, thus minimizing the lengths of secondary distribution cables and buses. Lengths of cables and buses are minimized, reducing the likelihood of faults and improving voltage regulation.

The switchgear is composed of the compartment body & center located withdrawable parts. The compartment body of switchgear is divided into four independant compartments.The protective level of the enclosure is IP4X. While the protective level is IP2X between the compartments and when the door of circuit breaker compartment is open.variable scheme are available such as overhead in-coming feeder and outgoing feeder, cable incoming feeder and outgoing feeder and other functions.A number of power distribution equipment with different functions could be analyzed after arrangements and combination of various schemes. The erection, adjustment and maintainance could be undertaken in the front of switchgear so that the switchgear could be back to back combined together in double arrangement and mountained against the wall.It has a high flexibility and safety with less floor space.

NUCON Transformers area proven as global technology in transformer. This technology with our expertise in transformers has resulted in a large range of very compact and cost efficient transformer. Transformers are available with off-circuit tap changer and / or load tap changes for voltage regulation.  Salient Features Better shield circuit strength Compact design Durable Optimum losses Use of magnetic shields to control strong flux Low flux density to withstand severe over excitation Thermally upgraded paper to improve transformer life time Insulation dressing optimization using FEM analysis Denergized tap changes (DTC) are typically provided in transformers optionally but load tap changes (LTC) are also available Available fluids : mineral oil and luminal oil customized design   Stadard Features Transforming medium voltage into high voltage levels Based on tried and tested technologies Meeting the latest I.E.C. technical specification Large overload capability depending on the ambient temperature Large overvoltage capability on generator side to withstand the overvoltage coming for load rejection Customized solution Satisfying specific customer requests Equipment for indoor and outdoor usage

Transformers are tailer-made products and the deisgn varies with the impedence levels (constant Ohmic and constant percentage), transmission voltage and cooling requirments. These are normally provided with on load tap changer for voltage variations. For long distance ruler power distribution lines, speacial autotransformers with automatic tap changing equipments are inserted as voltage regulations, so that customers at the far end of the line receive the same average voltage as those closer to the source. The variable ratio of the autotransformers compensates for the voltage drop along the line.  Salient Features Thermally upgraded paper to improve transformer life time Low flux density to withstand severe over excitation Use of magnetic shields to control strong flux optimum losses Better shield circuit strength enviornment friendly   Stadard Features Base on tried and tested technologies Meeting the latest I.E.C technical specification Large overload capability depending on the ambient temperature Large over voltage capability on generator side to withstand the overvoltage coming for load rejections customized solution Satisfying specific customer requests Equipments for indoor and outdoor usage
