Power tools are tool powered by an electric motor, a compressed air motor, or a gasoline engine. These are classified as either stationary or portable. These are used in industry, construction and around the house for cutting, shaping, drilling, sanding, painting, grinding, and polishing. Power tools for metal working are usually called machine tools. The list of power tools include air compressor, band saw, crusher, drill, disc sander and heat gun.

Power Transducer is designed for continuous monitoring of 3-phase system. Power transducers are designed to provide a controlled output that is proportional to the average being drawn from a power source. These devices are specifically targeted to provide an efficient solution to most power sensing needs. Power transducers are based on sensing the voltage & current. Its feature include active & reactive power sensing, DIN rail or panel mount and 0 - 5 VDC & 4 - 20 mA DC outputs.

Power Transformer is used to refer to those transformers used between the generators and the distribution circuits, and these are usually rated 500 kVA and above. Power transformers are selected based on the application, with the emphasis towards custom design being more apparent the larger the unit. They are available for step-up operation, primarily used at the generator and referred to as generator step-up transformers, and the step-down operation, mainly used to feed distribution circuits. Power transformer is available as single-phase or three-phase apparatus. Transformers intended for indoor use are primarily of the dry type but can also be liquid immersed. For outdoor use, transformers are usually liquid immersed.

Power transmission structure is suitable for miniaturization and weight reduction of small tillers. A small tiller comprising a transmission case bent substantially in a doglegged shape as seen in a side view and interlocked with a prime mover. It comprises of a traveling section disposed in the front of the transmission case, and a tilling section disposed in the rear of the transmission case, wherein the drive shaft of the transmission case is interlocked with the output shaft of the prime mover through a speed change mechanism. It is supported with an axle for driving the traveling section and a tilling shaft for driving the tilling section are individually interlocked with the drive shaft of the transmission case, so that the power from the prime mover is transmitted from a single drive shaft of the transmission case to the traveling section and tilling section.

A power transmission tower is a tall steel lattice structure used to support overhead electricity conductors for electric power transmission. A rigid steel tower supports a high-voltage electric power transmission line, having a large enough spacing between conductors, and between conductors and ground, to prevent corona discharge.
