Most of us can not imagine life without devices, simplifying household chores – a food processor, microwave, washing machine and dishwasher, fridge and other necessary equipment. Our crowded housing items that make life better. You know that among all of them have in common? That's right: electricity. So what is it like to electricity? It is odorless and invisible, is the result of movement negatively charged particles on a closed circuit. We often do not pay attention to it in everyday life, but if the current suddenly ceases to run on the wire, all useful and necessary things we will turn into a pile of scrap metal. In fact, anyone remember what happens in the apartment when the light goes out for several hours and remembers that impotence, which he feels – pitch-darkness, nothing more. And all this just because of one thing – the lack of electricity. It is not easy to imagine, but there were times when the electricity does not yet exist, and people used to light the candles of their homes.
It was beautiful, but it is not safe, and many lost their homes due to careless handling of fire. Only in 1733 the French scholar Du Fay discovered negatively and positively charged particles, the effect of which was later called 'electricity'. But the electrons (negatively charged particles) are not move through the wires themselves – to ensure that they have moved away, they need a driving force. It was such a force and is due to power generators. Then 'revived' electrons, crossing the wires, are transformers, and then – straight into our house. Even though its usefulness and indispensability, with electricity trifled with. For this reason, every person must learn the techniques of safe use electricity and to prevent their violation. One of the major hazards that can cause a person to death harm – an electric shock.
Electrical shock can occur when a person touches the bare wire under tension. Wire without insulation – this is a gross violation. Isolation or a complete replacement of the wiring – this is a solution that can protect people from injury and save lives. The main methods designed to protect people from the danger of electrical shock: prevention of damage to the network, the division of power grids, grounding, insulation of bare wires. Electrical insulation – one of the most effective methods of protection against electric shock. It consists in winding wire layer of dielectric material. Isolation may be different, but the most effective – Reinforced insulation, made of several layers of dielectric material. Only such insulation can guarantee that a random contact with live element will not lead to electric shock. Moreover, anyone worth remembering that all electrical work must be carried out only specialist. Electric wiring Kiev will perform, carry out the separation too extensive electrical network, isolating it and thus ensure the safety of your home. Today, electrical service can afford any, so calling an electrician at home – critical decision a person who care about their safety and security of their loved ones.
