3 ways wire insulation at home

Precautions

For starters let's talk about what rules must be followed live by their during isolationhands.Firstly, it is strictly forbidden to isolate the live conductors.You must always switch off the circuit breaker in the distribution board.Second, to protect the point of connection is necessary to use only those materials that are recommended rules and RB have been tested GOST dielectric strength, operating temperature, flammability.

We strongly do not recommend to use as insulation tape, sincethis material has no sufficient insulating properties.Now we look at how to properly insulate the wires in the home, as well as to provide you the most reliable insulating materials.

Review insulating materials

Today for insulation exposed veins is recommended to use materials such as:

• PVC insulating tape.It has good elasticity, but in a wet environment quickly becomes limp and come unstuck.Recommended for wire insulation in dry conditions, and if you want to make a color-coded wires (there is an insulating tape of different colors that can be used to indicate the phase of zero and the ground at the end of the conductor).
• HB electrical tape.The cotton material, which is a more reliable option not only for the home environment, but if you want to isolate the conductors from each other under the hood of a car.HB advantage of tape is that it is more resistant to moisture, low temperatures and dirt.
• shrinkable tubing (HERE).Shrink is one of the most modern and reliable insulating materials.It is recommended that you use when you want to insulate the connection of electrical wires not only at home but also in the ground, under water, in the car.Universal isolator, which we recommend that you use at home!
• Caps PPE.Insulation sizami used if you do twist wires.The insulating properties, of course, not like at the heat-shrinkable tube, but still help to protect the exposed wires in the junction box under the chandelier and plasterboard.

Here we provide the most reliable and popular among electricians insulating materials.Then we'll show you how to properly insulate the exposed contact with insulating tape, shrink and caps.

Instructions for use

insulators Well here we come to the fundamental question of the article - wire insulation technology with their own hands.Since there are several materials, we look at each and describe how to isolate the loose strands.

If you use electrical tape, you first need to make a good twist wires.If stranded wire is recommended in addition to solder them to a more secure connection.Further twisting bends to one side, as shown in the photo, and then an insulating tape is wound on the exposed portion of at least 2 layers.This technique is often used in an apartment, even experienced electricians.Electrical tape can be used when connecting wires in the junction box, the chandelier, with the transference outlets and even under the plaster, if the junction is located in the junction box.

heat shrinkage insulate bare wires and not difficult.The main important thing to remember - the tube must be fitted on one of the conductors prior to splicing.After soldering or twisting tubing wear (it is so called) you could not.When the contacts are connected, the receiver need to pull on the connection naked, and then heat the building hairdryer.

If the dryer is not at hand, allowed heating ordinary lighter, more importantly, make sure that shrinking tightly pulled on the cable.Use tube HERE recommended by immersing the conductor in the water (for example, if the power cord is damaged in the deep well pump).In addition, shrinking is used for cable laying underground, if you want to connect the underground wiring.It is also recommended to insulate the wires of this material in the bathroom, wooden house, bath or on the street, to reliably protect the connection from the water.

Caps PPE is better to use when installing the wiring in the house and apartment.Siza compact and can quickly be insulated twist.All that is needed - screwed the cap on the wire until it stops, as shown in the photo below.

If you want to protect twisting thin wires, such as headphones, use electrical tape is not advisable, becauseit will not fit snugly.In this case, you can do without the tape, using the normal superglue.All you need to do - gently drip glue on the exposed portion of the small conductors.It is not recommended in a 220 Volt such a way asadhesive, in fact, like silicone sealant, fast fall off.By the way, the adhesive gun is also not necessary to isolate the core, for the same reason.

For additional insulation of the cable from a rabbit, a cat or a puppy in the house (pets love to chew on the wires), it is recommended to use tin foil.On the other ways to protect the wiring from the animals, read the corresponding article!

Here we have provided all the existing methods of insulation of bare living with their own hands.How do you see yourself insulated wire underwater in the wall and the ground is not so difficult, the main thing to choose the material for insulation.Finally we recommend you in wet rooms and outdoors in addition to protect the wiring flexi hose, which further protects the connection point, so as not to spill water on the exposed contacts.
