Auto Transformers - Egytrafo Group - Auto Transformers

Auto Transformers with (manual/automatic) tap-changing equipment are inserted as voltage regulators 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 Auto Transformer compensates for the voltage drop along the line 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 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 – winding transformer The resistance and reactance are less compared to a two – winding transformer and hence it has superior voltage regulation Volt-ampere rating is more compared to a two – winding transformer It is possible to get smooth and continuous variation of voltage

Nickel Cadmium Batteries - Egytrafo Group Ni-Cd

Nickel Cadmium Batteries (Ni-Cd) up to 800 Ah:- The 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 Different types:- * Low discharge cells (KPL) battery: The L type is designed for applications where the battery is required to provide a reliable source of energy over relatively long discharge periods, Normally, the current is relatively low in comparison with the total stored energy * Medium discharge cells (KPM) battery: The M type is designed for applications where the batteries are usually required to sustain electrical loads for between 30 minutes to 3 hours or for “mixed” loads which involve a mixture of high and low discharge rates. Active Material:- Nickel Hydroxide& Cadmium Hydroxide.
