What Should We Pay Attention To During The Installation Of Metal Cable Connectors?

In the power system, Nylon Cable Gland is a very common accessory. This connector is mainly used in outdoor products and large and medium-sized remote control machinery. It can provide a relatively safe and reliable connection effect. However, what should we pay attention to during the installation process? Let's take a closer look.

1. Select the appropriate connector material according to the specific model and specification of the connector. At present, the more common materials are stainless steel and brass. Different materials have different performances. Even if they are the same materials, the quality of the connectors is uneven due to the uneven quality of the materials. In order to ensure the quality of the connector, it is recommended not to be cheap and try to choose connectors from big brands.

2. When installing, try to avoid installing on rainy days and weather with high air humidity. If the humidity in the air is relatively high, moisture or water droplets will enter the inside of the connector, resulting in a decrease in the insulation performance of the connector insulation, and even a short circuit accident.

3. Before installation, you should carefully read the manufacturer's product manual and connect according to the method in the manual.

4. When installing the terminal connector of a single-core armored cable above 0kV, pay attention to grounding the steel belt at only one end.

What should be paid attention to during the installation of metal cable joints?

5. When crimping, pay attention to the force of crimping. It should not be too strong. Just use a little force to crimp it into place. There will be some protrusions on the copper end surface after crimping. These protrusions must be flattened with a file, and no burrs should remain on the surface.

6. When installing heat shrink cable joints, a blowtorch is needed. The blowtorch cannot be facing only one direction. It should be moved back and forth to try to make the joints evenly heated.

7. When installing cold shrink cable joints, the size cannot be arbitrary. It should be done strictly according to the instructions on the drawings. When pulling out the supports in the reserved tube, you should be careful.

During operation, the cable may heat up due to resistance. Although the resistance value of the resistance is generally very small, sometimes this heat will cause the cable to heat up, and the cable's ability to withstand high temperature operation is limited. Once the temperature is too high, it may cause accidents such as short circuit and fire. How to prevent cable fires caused by overload?

1. When designing the line, you should determine the approximate capacity required by the site and leave some room for future capacity expansion, so as to select the appropriate type of cable. If the capacity is relatively large, you should choose a thicker cable. If the type is not selected properly in the early stage. It may lead to problems of difficulty in future use and maintenance. Randomly laying the line may cause overload during future use.

2. When laying the line, it should be strictly in accordance with the relevant specifications. The line laying conditions will directly affect the heat dissipation of the cable. When laying the line, it should not be stacked. At the same time, in order to avoid poor heat dissipation, there should be no flammable materials around to avoid fire.

To sum up, when installing metal cable joints, first of all, you need to pay attention to selecting the appropriate joint specifications and models, and secondly, you need to strictly install them in accordance with relevant specifications. There are special installation specifications for the installation of special joints, which also need to be strictly followed during installation.
