(Ni-Cd battery or Ni-Cad battery) is the most reliable battery system available in the market today
It is not surprising, therefore, that the Nickel Cadmium battery has become an obvious first choice for users looking for complete reliability, long cycle life, fast recharge, exceptionally long lifetime, low maintenance, low life-cycle cost, wide operating temperature range, environment friendly.
Product Description:-
Capacity up to 800 Ah.: block battery capacity is rated in ampere-hours (Ah) and is the quantity of electricity at +20 �°C (+68�°F) which it can supply for a 5-hour discharge to 1.0 V after being fully charged for 7.5 hours at 0.2 C5 A.
Cell voltage: The nominal voltage for this electrochemical couple is 1.2 V
According to IEC 60623 Standards :
There are a number of methods which are used to size Nickel Cadmium batteries for standby floating applications.
The method is the IEEE 1115 recommendation (accepted internationally)
Automatic Voltage Regulator (AVR)
AVR
Automatic Voltage Regulator (AVR) with on Load Tap changer
The On Load Tap Changer, automatic voltage regulator (AVR) is used to compensate the voltage drop in the electrical networkâ?? so that customers at the line end receive the same average voltage value as those closer to the source.
The voltage value reduction affects the operational quality of the rotating machines and increases the losses due to the high current drawn due to the voltage reduction. It also affects the quality of the illuminating system.
EGYTRAFO Group produces the Automatic Voltage Regulator (AVR) with rating up to 630 A & 9 tapping positions.
-The AVR is flange mounted (ON TANK) or (IN TANK) type according to the rating of the transformer and a remote tap changer control cubicle (RTCC)
Our ranges are up to 630 A, up to 22 KV and more than 5 taping positions on request.
Automatic Voltage Regulator (AVR) applications:
you can use it as a safely starting machines such as induction motors and synchronous motors
Also, boosters to give a small boost to distribution cable for compensating the voltage drop
you can get the same advantage of the Variac
Automatic Voltage Regulator (AVR) advantages:
Increased KVA rating for a given size and mass
Less amount of copper
Due to the smaller size, the cost is less compared to a two â?? winding transformer
The resistance and reactance are less compared to a two â?? winding transformer and hence it has superior voltage regulation
The Volt-ampere rating is more compared to a two â?? winding transformer
It is possible to get a smooth and continuous variation of voltage
Dry Transformers up to 3.6 MVA, 33 KV (Indoor & Outdoor)
EGYTRAFO Group produces a wide range of Dry type Cast Resin transformers up to 3.6 MVA, 33 KV which are suitable for indoor and outdoor installation (inside an enclosure with certain IP) and ambient temperatures up to 45oC.
