Cable Gland Manufacturers: Features of Cable Glands, Installation Matters and How to Use Cable Glands

The key points of cable joint installation, so that friends who don't know how to install can understand.
 

Waterproof cable connector is a common cable accessory. In order to ensure higher safety and sealing during use, the following points should be paid special attention to during installation and use:

1. Choose the appropriate connector material according to the type and specification of the required cable connector. Nowadays, the quality of the cable connector material is also uneven, but in order to ensure the quality of the cable connector, it is recommended not to be cheap. The cable connector manufacturer recommends choosing a reliable cable connector manufacturer's material.

2. The manufacturer of the cable joint warmly suggests that it is best not to choose rainy days when the cable joint is connected because the water ingress of the cable will seriously affect the service life of the cable, and even short-circuit accidents will occur in severe cases.

3. Be sure to read the manufacturer's product manual carefully before making the cable waterproof joint. This is especially important for cables of 10kV and above. Before doing it, think about all the processes before doing it.

4. For terminal joints of single-core armored cables above 10kV, remember that only one end of the steel strip can be grounded.

5. Don't use too much force when pressing the copper pipe, as long as it is crimped in place, there will inevitably be many raised spots on the copper end after crimping. This must be flattened with a file, and no burrs should be left.

6. When using the blowtorch for heat-shrinkable cable joints, pay attention to the blowtorch moving back and forth, and cannot only blow the torch in one direction continuously.

7. The size of the cold-shrinkable cable joint must be strictly in accordance with the drawings, especially when pulling out the support in the reserved tube, you must be more careful.

How to use the cable gland？

1. Unplug the cable from the connector;
2. Meet the connection length according to the specification requirements;
3. The cable joint manufacturer tells you that the next step is to start the connection, imprison it with hydraulic pliers, and polish it smoothly;
4. Wrap tape, apply silicone paste, and heat shrink;
5. Put on the protective net and continue to wrap the tape.

What is gland for control cable?

The cable joint is a component in the cable line, which is used to realize the connection of two cables and improve the electric field at the end of the two cables. Long circuits must pass two or more lengths of cable together, which requires straight connectors. A straight-through connector is an accessory that connects two cables to form a continuous circuit, especially a connector in which the metal shell of the connector is electrically continuous with the metal shield and insulation shield of the connected cable. In order to reduce the induced electromotive force of the metal sheath, the high-voltage line needs an insulating joint to realize the cross-transposition connection, so as to eliminate the circulating current generated by the induced electromotive force.

What are the advantages of cable glands?

1. The use process is simple, the viscosity of the rubber is moderate, easy to mix and pour, and can be used to fill small orifices or parts.
2. High and low-temperature resistance, after vulcanization, the cable waterproof joint product maintains elasticity in the temperature range of -50°C to +250°C, and can be used for a long time.
3. Hydrophobic and moisture-proof, salt spray resistance, ozone resistance, and weather aging resistance are excellent.
4. High dielectric strength, low dielectric loss, excellent arc resistance, and corona resistance. Even in the water, it has waterproof, anti-corrosion, and insulating functions.
5. The strength of the vulcanized rubber is moderate, and it can be broken apart by hand, which is convenient for cleaning and maintenance. After overhaul, the silicone rubber poured in can be integrated with the previous rubber material to maintain good sealing performance.
6. Insert the circuit detector probe into the hose joint, and it can be tested at any time. After the probe is pulled out, the rubber will quickly fill the gap.
