In the work of an electrician, one of the most frequent operations during electrical installation is stripping and connecting wires. In such seemingly simple actions, there are a number of nuances. Yes, and it is not recommended to remove the insulation from the wires with a knife, because if you do not have developed skills, you will damage the conductive wires. And this will lead to problems in posting in the future. Read about stripping tools in this article.

Fans will answer that you can remove the insulation with a conventional knife. You can do it this way, but there is a small problem. When stripping insulation from a soft wire with multi-wire cores, especially with cross-sectional conductors up to 1.5 sq. mm many make a mistake - cut the veins. As a result, the contact area decreases and the cross section due to the fact that the number of veins decreases. When stripping insulation from wires with monolithic or single-wire cores, another problem arises - the cores are notched ...

The modern world is so electrified that the number of wired connections and electrical networks can no longer be counted. Consumers of various purposes have not been connected with bare wires for a long time, and even power lines are no exception.

SIP wire (short for "self-supporting insulated wire") is successfully used in many networks, industrial and domestic, which is by no means accidental. The fact is that wires of this type differ in a number of advantages, which we will talk about later. When compared with other brands of wires, the SIP is truly unique. It is designed to transmit electrical energy, while it is positioned just like a wire, and not like a cable, although it carries itself, has insulation, is multi-core - almost like a cable. Take for example a wire of the SIP-1 brand 3x150 + 1x70. There are three insulated cores ...

The oscilloscope is the eyes of a master repairing electronics and a radio amateur. But the cost of advanced models is incomprehensible for beginners and even for many experienced craftsmen. For example, not the coolest digital oscilloscope UNI-T UTD2025CL with two channels with the ability to transmit signals with a frequency of up to 25 MHz costs more than $ 200, and some RIGOL MSO2302A-S is a powerful two-channel oscilloscope with two channels and a bandwidth of 300 MHz with a recorder function costs almost $ 4,000.

But where to go to the simple peasant? For starters, you can turn to the products of manufacturers from the Middle Kingdom. There are a lot of portable oscilloscopes on Aliexpress with different characteristics and capabilities, we will consider some of them in this article. To begin with, if we talk about portable oscilloscopes, then in almost all cases these are digital devices. Like any measuring device, oscilloscopes have a number of characteristics ...

An ultrasound scanner or multifunction protection device is designed to provide instant disconnection of network equipment, provided that there is a certain increase or decrease in voltage in the single-phase network from which this equipment is powered. Thus, the equipment of an apartment, garage, office, home, etc. is protected from the harmful effects of short-term power surges.

These jumps can be caused by factors such as the inclusion of electric motors, electromagnets, magnetic starters, powerful devices, etc. fed from the same network. A quick shutdown by means of an ultrasound device prevents equipment failure and can prevent a possible fire and, in some cases, even a fire .Being connected according to this scheme, an ultrasound transducer can serve as a pulse relay. If the neutral conductor breaks off, the load is immediately turned off, and when the neutral conductor is connected again, the ultrasound transformer will turn on the load ...

Pin power connectors are widely used today to connect external power supplies to various devices: electronic medical devices, table fans and lamps, chargers, portable speakers, etc. In many devices, having a built-in power supply is simply not convenient, and therefore it is made external, which is sometimes much more practical. In addition, one power supply can be used for alternate use with several different devices, since the pin connectors have a unified format.

Assembled, this connector consists of a plug and socket. The plug itself includes two parts: a plastic case and a cylindrical contact with a pair of terminals for soldering the wire coming from the power supply. The conclusions for fastening the wire can be made not only for soldering, but also in the form of a terminal block. The socket of the connector, as the name implies, has a pin and its own housing ...

For the implementation of any projects, whether it is a smart home, industrial automation, a device for outputting computer systems, or a simple clock, you will need an output device. A simple option is seven-segment LED indicators. But such an implementation would be inconvenient to use. To make the system modern and convenient, you need to use full-fledged LCD displays. In this article, we will talk about Nextion displays, what it is, how, and why they can be used.

The manufacturer positions the Nextion touch displays as HMI - Human-machine interface, which in Russian sounds like a "Human-machine interface." This is the name of any device with the help of which human-machine interactions take place: parameter monitoring, control of actuators, data entry, etc. In practice, this is not just a display, but a device with a 32-bit ARM microcontroller on board, which "can" not only display data ...

An electrical insulating tape (electrical tape) is a consumable material intended for insulation of wires and cables during various electrical and repair work. In the first half of the 20th century, the developers of the American company Minnesota Mining and Manufacturing decided to develop an electrical insulating tape that would be not just a tape, but a self-adhesive tape.

At first it was decided to create such a PVC-based tape, but it turned out that tricresyl phosphate (at the base of the plasticizer) makes the surface of the tape very oily and leads to the destruction of any adhesives that are applied to it. Later, chemists of the company found a new approach - they began to produce tape based on rubber and without sulfur content. These first self-adhesive tapes were white and yellow. The white ribbon quickly became a thing of the past due to its instability to ultraviolet, it was replaced by black ...

Not always a stationary outlet is exactly at the place where you want to connect and use the appliance. Sometimes we just do not have enough wire length, for example, while working with a drill, or we decided to put the refrigerator three meters away from the wall outlet.

There is no way to do without an extension cord. For this, it was created - to allow us to use electrical appliances in places remote from stationary sockets. Needless to say, connecting a computer that requires several outlets at once.And where to get them, if not on the extension cord? The use of an electrical appliance with an extension cord can be permanent, as in the example with a computer, or temporary, as in the example with a drill. For a computer, we will need an extension cord with a multi-socket outlet, and even equipped with some kind of surge protector, if only so that with the click of a button it would be possible to immediately disconnect the monitor from the network ...
