How to choose an electrical outlet so that it lasts faithfully for many years?

By design, almost all sockets are the same. As a rule, they consist of a body, a block, to which springy contacts and terminals are attached, to which, in fact, current-carrying wires are screwed.

Sockets are for industrial use, for connecting powerful, energy-intensive consumers. Such outlets, depending on the load, can be rated for current up to several hundred amperes. In this article we will consider sockets designed for use in everyday life ...

Carbon thermostat UNIMAT-a new system for the manufacture of underfloor heating, space heating. It has a unique adaptability property and saves energy.

One of the leading companies in South Korea - GT3 has developed and launched the production of a new system for underfloor heating.This carbon rod based system is called Unimat. Another name for this system is “thermomat”.

Structurally, UNIMAT thermomat consists of carbon-fiber rods connected in parallel and is available in rolls up to 30 m long. The rods are designed with a protective coating that protects them from aggressive substances and makes the entire system electrically safe ...

Description of the purpose, principle of operation of infrared motion sensors. How to choose a motion sensor to fit your needs.

Today, the issues of applying energy-saving technologies in everyday life are becoming increasingly relevant. The cost of electricity consumed can be significantly reduced by using motion sensors in everyday life (“PIR” - from English - “passive infrared” - “passive infrared”).

Infrared motion sensors designed to close the power circuit in the event of the appearance (movement) of a person (car, etc.) in a controlled area. Depending on the version, the sensors can be used both indoors and outdoors. Household motion sensors use in their work the principle of constant monitoring of infrared radiation in the tracking zone. When an object appears, of sufficient mass and with a temperature exceeding the surrounding by five degrees Celsius, the overall picture of the thermal field changes ...
