In this article, we discussed the importance of Electrical conduits, different types of electrical conduits, Maximum no. of cables in electrical conduit 20mm, 25mm, 32mm. Minimum distance between saddle clip for a conduit. Why some LED light works even when switch is OFF. This may be due to the electrical induction from another cable in the same conduit. Avoid it draw less than maximum allowed cables in the conduit. Read more
Flame retardant cables are cables that are designed to resist the spread of fire into a new area. They do not propagate flame & fire. Halogen-free cables are cables whose insulation materials do not contain the elements of the halogen group like chloride. These are Non-Toxic & Non-Corrosive. For example, one of the most common insulating materials is polyvinyl chloride (PVC). This is because as non-conductors, halogens such as chlorine are excellent insulators and are therefore often used as the insulator material for cables. When PVC gets burned, it produces carbon monoxide, dioxins, and chlorinated furans. Dioxins and furans are Read more
A BLDC or brush-less DC motor is an electronically commuted DC motor which does not have brushes.This is Upcoming technology which will be replacing many for are old home appliances with induction motors due to the power-saving feature of this technology. In the BLDC motor, the electronic controller provides calculated pulses of current to the motor windings in order to control the speed and torque of the motor. Using this speed control technique we can operate the motor at required output speed, thereby saving the power requirement.In this blog, I have explained about BLDC motors working, types, structure and making.

Electrical cables can be classified into different Class as per IEC 60228 according to the conductors flexibility and thermal effects.Class 1 => Solid conductorClass 2 => Stranded conductorClass 5 => Flexible conductorClass 6 => Very Flexible conductorAs per above mentioned IEC 60228, according insulation conductor cable standard Class 2 and Class 5 conductors are differentiated as per its conductor hardness. Class 2 is known as twisted round cable, Class 5 is known as soft conductor. As class 2 cables being harder and less flexible are used for fixed or with less mobile design like permanent building wiring and house wiring. Read more
We have been using electricity for many year, but still now electrical power reaching our homes and factories are not perfectly safe to use. These are many due to our electrical power system during transmission and distribution is exposed to many critical conditions like under-voltage, over-voltages and voltage surges due to lightning strikes, heavy system short circuit, abrupt switching conditions. Among these issue, the major concern to everybody is sudden over-voltage condition which can cause major damage to your equipment. This leads to our today's topic of discussion which is necessary to install a device that guarantees protection of our Read more
