Drop out fuses and load-drop fuses are outdoor high voltage protection appliances. It is installed on the high voltage side of the distribution transformer or on the branch line of the distribution line. used as a short circuit of the transformer and the line, overload protection and split load current.
A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to “step up” or “step down” voltages and works on the magnetic induction principle. … A voltage is then induced in the other coil, called the secondary or output coil.
A suspension clamp for an overhead electrical cable includes a clamping member which clamps the cable along a portion of its longitudinal sides. Arms extend outwardly from the opposed lateral sides of the clamping member along the direction defined by the cable
A current transformer (CT) is a type of transformer that is used to reduce or multiply an alternating current (AC). It produces a current in its secondary which is proportional to the current in its primary. Current transformers, along with voltage or potential transformers, are instrument transformers.
Ground rods can be made with many different materials, but copper is the most common materials used for residential installations. Ground rods are very good conductors of electricity and allow any dangerous electricity to flow to ground, taking the danger away from you and the electrical panel.
Bimetallic Lugs are mostly useful where an aluminum cable has to be terminated by a copper bus bar or copper contact. If Cable Lugs of only copper or aluminum are used , a galvanic action occurs due to dissimilar contact. The use of bimetallic lugs thus ensures a technically sound and durable joint.
There are three types cable connectors in a basic cabling installation techniques: twisted-pair connectors,coaxial cable connectors and fiber-optic connectors. Generally cable connectors have a male component and a female component, except in the case of hermaphroditic connectors such as the IBM data connector
For connection of Cable to Switchgear Terminal, Transformer Terminal, Poles etc. termination kits are required. … Termination can be for XLPE & strong PILC Cable and can be used in extreme hazardous atmosphere conditions.
When suspension string is used to sustain extraordinary tensile load of conductor it is referred as string insulator. When there is a dead end or there is a sharp corner in transmission line, the line has to sustain a great tensile load of conductor or strain.
These insulators are used for the transmission and distribution of electric power at voltages up to 33 kV. A single-pin insulator is deployed to transmit voltages up to 11 kV but higher voltages require two-, three- or four-piece pin insulators
fuse disconnect switch(DS) outdoor high voltage isolate switch is the high voltage switch equipment of composite strudcture, is suitable for outdoor 22KV line net with voltageand no load, to make opening and close. With type manual operate machinery, can avoid earth line with power and composite flash-locks ets.
A surge arrester is a protective device for limiting voltage on equipment by discharging or bypassing surge current. An arrester does not absorb lightning or stop lightning. It diverts the lightning, limits the voltage and protects the equipment installed in parallel
Transformer can transform the voltage of a network into the voltage matching the system or load and fulfill power transferring and distributing.Taking the place of transformers with silicon steel core, AMDT can be widely applied in outdoor power distribution networks systems, which is magnificently energy saving and can lessen air pollution. It is especially applicable for areas with insufficient power supply and fluctuating load and where daily maintenance is hard. Since the transformer adopts a fully sealed structure, the insulating oil and the insulating medium are not polluted by the atmosphere, so it can be carried out in a humid environment, making the ideal power distribution equipment in the urban and rural distribution networks.
ATS (Automatic Transfer Switch) panels detect when the mains electricity supply fails and sends a signal to the emergency generator control panel to start the generator. … All ATS include a 4-pole automatic changeover device, phase failure detection, timers and a generator run relay. We EEPS will design base on what capacity you need.
Medium Voltage power cable is used to transmit and distribute power in power transmission and distribution system of 22kV or Higher. It is generally applied to the fields including power, mines, construction, metallurgy, petrochemical industry and communication in complete replace of oil immersed paper insulated power cable. Here EEPS we have stcock all types of MV-Cable.
In an electric power system, switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream.
