Tips and NSHVI NSHVI-2, the purpose and proper application

The tip of the pin sleeve isolated - in this way the abbreviation stands for the given product. It made specifically for crimping the ends of the copper stranded wires. Their use allows you very easily and securely fix the switching device flexible wire to any terminal. The use of special tools and mounting lugs significantly accelerate the process. In this article I will tell you about the existing types and sizes of nozzles NSHVIAs well as how to use them correctly.

Existing types of tips

On the electrical market can find three varieties of products, namely:

NSHVI - Pin sleeve caps isolated;

NSHV - pin bushing tips, but without the insulating material;

NSHVI-2 - the same lugs insulated but intended for the connection of two laminated copper wires.

Since lugs without insulation is practically used, the further we will talk about it NSHVI and NSHVI-2:

What constitutes tip

This product is made of two parts, namely:

1. The conductive tube made of tin-plated electrolytic copper.

2. The insulating skirt made of polyamide.

The use of this nozzle prevents the wires by displacement when applying a screw clamp. NSHVI issued calculated on the cross section of 0.25 sq. to 150 mm square. mm. In this case, the sleeve itself must undergo a galvanic tinning.

Become familiar with the size and color-coded, you can in this table:

A product designation stands as follows: NSHVI 2.5-8 - Tip pin bushing insulated wire size of 2.5 millimeters, 8 millimeters non-insulated part (the most common length of the tip section to 4 mm²).

distinction NSHVI from NSHVI-2 lies only in the fact that they have different sizes isolated flyanets, in the first case it is intended for single wire, and the second for two cables.

Where to use and how to properly wire pressure test

NSHVI saves flexible conductor of kinked (damage) of the individual cores while tightening the screw connection. After hauling strands without such a tip can bring it to kink and, subsequently overheating and burning-off contact.

And when using the terminal clamps the tip of the tip tube and not the actual vein. In this case, the strength of the contact does not suffer, but on the contrary increases.

But the process of breaking itself, though very simple, but requires strict compliance with the algorithm of actions:

Before compression must perform sweep conductors, wherein the length of the stripped wires must coincide with the length of the tip bushing.

Next take tip, and its diameter should strictly match the diameter of the stripped core and inserted into the handpiece so that the insulation is rested against the top of the sleeve.

Thereafter, the tip insert prepared in a groove of corresponding diameter press mites not to touch when broken down in the insulating skirt.

After that, check to see if wires protrude from the tip if the stick out, just cut them flush with the edge of the sleeve.

All your connection is fully prepared.

crimping algorithm NSHVI-2 no different from the above action plan. Remember, these tips are designed to connect two wires, which will be further tightened by the clamp. But as an independent connection (capacity) of wires it can not be used for this purpose there are crimping sleeves.

Such a method of crimping is ideal in cases where there is assembled the electrical panel, and a specialist it was decided to use it is a flexible wire. And also in the assembly of all types of perenosok and other equipment to be connected via a flexible supply cords.

That's all I wanted to tell you about the tips and NSHVI NSHVI-2, as well as their application. If the article was useful to you, then put his finger up and thank you for your attention!
