SIP connectivity options to a modular machine

Now the overwhelming number of cases as an input in the house using SIP with conductor cross-section of 16 square millimeters. And often there is a question: how to connect it to the machine. In this article, we will focus on the connection options that are widely used, as well as the most correct option.

The requirement for power sales

Here we shall not consider this as a variant of the execution transition from aluminum to copper via piercing clamp (or transition terminals, etc.).

Because in most cases gorseti (Energosbyt) require that input had no discontinuities from column to induction machine (or a counter). Although he is correct.

Connection options to the machine SIPA

First, let's find out what are the options for connecting aerial bundled cable to a modular machine:

1. Easily connect SIPA to the machine without any additional elements.

2. SIPA connection to the circuit breaker by changing the contact surface core.

3. Connecting to the SIPA load switch or automatically with a specialized presser bar.

4. Connecting SIPA after pre-crimping sleeves lived

Let us now discuss each option in more detail.

Easily connect SIPA

We begin our analysis with the easiest (for the installer or inspector gorsetey) option, namely to connect SIPA without any tricks directly to the machine. Such an embodiment might use 95% of cases.

After clamping the terminal machine is performed (again, in most cases) with the obligatory tinkering, and it allows you to connect both copper and aluminum conductors.

By the way, when buying a machine, pay attention to the material from which made the contact group, as there are machines where the clamping terminal is made of copper.

This connection is quite easy and simple, but at the same pros it completely exhausted. Next start solid disadvantages

Since the NIC has a multifilamentary structure and a circular shape, then the clamp in its square terminal, the contact area is small, pinched and deformed strands that can subsequently lead to weakening as a result of contact and to the space heating connection.

To avoid this, it is necessary periodically (at least once every 10-12 months) stretching such a connection. But as with the meter box or the opening is sealed Energosbyt machine, no one will give us constantly breaks the seal and carry out such an audit. It turns out in this case, can only wait and wonder "survive" such a compound to replace the metering device or not.

Connecting NIC by changing the contact surface

The second embodiment, which is only slightly more complicated first, a connection conductor which is pre-curled even stronger

This creates a denser placement lived, that during clamping the automaton gives SIPU "collapse" and thereby create a more reliable connection. But this is still weak in terms of the contact area. It also says that with the passage of time the heating is provided and significant loads. And not the fact that such a connection option "will make it" to replace the metering device.

Connecting SIPA via load switch or machine with a special form of contact

This option I think the most preferred and here's why:

In order to create a reliable connection without any additional "problems" you just get together with the opening machine (or instead him, if you continue all groups protected by their circuit breakers) load switch or take the machine with the special form of clamping sponges.

This semi-circular shape perfectly round girth vein SIPA and thus will create a secure connection with the sufficient contact area, reducing the heating to be an acceptable level and the compound lasts long time.

Connecting SIPA after pre-crimping lived further elaborated sleeves

Another option is connected properly, SIPA is its pre-crimping sleeves further elaborated:

A revision is as follows:

Divide the sleeve arbitrarily into two halves, one half, we press-fit our SIP cable, but the second part of the need to perform the following manipulations:

We need to create at this point the tip of the pin, to attach the second part of the tip of the pin shape as shown in the photo:

Next, dress heat shrinkable tubing and insulate the open part:

All mix thoroughly ready and now SIP can be clamped in any contact machine.

In this article, all possible options for SIP connection to the machine have been considered. Hopefully, this article will provide you with useful and interesting. If yes, you will appreciate it Like.
