R- Core Transformers are 30 percent smaller, 30 percent thinner and 40 percent lighter than EI type transformers. Sizes are available from 5VA to 1000VA. There are many applications such as office equipment, A/V equipment, medical equipment, CATV systems and electronic instruments. R-Core transformers are suitable for any product that can benefit from a high efficiency, streamlined transformer. Its major features include 90 percent efficiency, low leakage flux, small size and weight. Other features of R-Core transformers include rational design and high-grade material, and suitable for adaptors. Major advantages of R-Core transformers include high efficiency, small size, thin body, light weight, and standardization of production. This transformer delivers extremely low noise. Its insulating effect is excellent and its output power is large.

Pool owners don't think about protecting their pool's electrical equipment from storms. Certain disruptions may lead to fluctuations which may damage or destroy sensitive electrical components due to extra voltage. Voltage surges are sometimes referred to as spikes. The spike can harm both high and low voltage pool equipment. High voltage equipment includes pool-pump motor, spa air blower, heat pumps, pool, spa lights and fiber optic illuminators. Low voltage power runs automation control panels, displays and actuator valves. The cost of replacing the equipment may be costly. Homemakers can purchase surge-protection devices to guard against spikes. Surge protection devices should be installed by a licensed, trained and insured electrical contractor. Warning: This job is not do-it-yourself. Surge protection devices can reduce the spikes on your pool equipment, but this equipment cannot safeguard direct lightning hits that may destroy the equipment.

Siemens energy and prysmian cables & systems, have bagged an order of EUR 87 million by Thanet offshore wind ltd. The two partners have to connect the Thanet offshore wind farm to British power grid. Siemens energy and prysmian cables will generate power for nearly 167,000 homes with a capacity of 300 megawatts. Siemens will construct an offshore substation platform which will have more than one power transformer. Prysmian will supply two three phase 132 kV high voltage sub sea cables to transport the electrical power to the grid connection point. Substations will also include high voltage and medium switchgear with the necessary protection and control technology. Substation will boost the voltage from 33 kV to 132 kV for transmission to shore. Siemens is equipping the substation, which will act as the grid connection point on the coast, with a system for reactive-power compensation based on static var compensator technology. In 2007, revenue from siemens environmental portfolio was nearly EUR 17 billion. Its revenue target for 2011 is EUR 25 billion.
