SINGLE COMPRESSION CABLE GLAND VS DOUBLE COMPRESSION CABLE GLAND
Single Compression Cable Gland -
These indoor and outdoor cable glands provide a waterproof seal for the external sheath of cables and are suitable for use with all varieties of armored and unarmoured cables.
The number of compression seals that a single compression cable gland and a double compression cable gland offer is the primary distinction between them.
A single sealing or compression mechanism on a single compression cable gland normally secures the cable by forcing it up against the gland body. For applications where an extensive amount of sealing is not required, this design is easier to implement and more frequently employed.
A double compression cable gland, on the other hand, has two seals or pressure mechanisms.
The first seal holds the cable in place by pressing it up against the gland body, while the second seal adds an extra layer of security by pressing up against the cable's inner sheath or insulation. This style provides improved sealing capabilities and is frequent. In a single compression cable gland - The compression motion forms a barrier around the cable, shielding it from dirt, moisture, and other outside factors whereas in a double compression cable gland its enhanced resistance against the entry of moisture, dust, and other impurities, it can be used in more demanding or dangerous conditions.
In conclusion, both single-compression and double-compression cable glands give strain relief and cable sealing, but a double-compression gland adds an additional degree of security because of its dual sealing mechanism. The decision between them is based on the particular application needs, the surrounding environment, and the required level of sealing and protection.
TYPES OF DOUBLE COMPRESSION CABLE GLAND -
- Single compression cable glands-
Cable glands that offer a single compression seal for cable security and protection are known as single compression cable glands. In most cases, they are made up of a gland body and a compression nut.
These glands provide an additional layer of compression for a more dependable and secure seal. They have a second compression seal that offers better defense against moisture, dust, and other impurities, such as a rubber or elastomeric ring.
- Barrier cable glands:
It's vital to prevent explosive gases or liquids from traveling down cable cores in hazardous settings where barrier cable glands are specifically built. To guarantee a high level of safety, they use several compression seals and barriers.
- Armour Cable Glands:
Cables having metallic armor, such as steel wire or tape, are utilized with armoured cables glands. They offer a twofold compression seal to contain and protect the armored cable's integrity.
- EMC cable glands:
EMC (Electromagnetic Compatibility) cable glands are made to ground and shield cables from electromagnetic fields. To lessen EM interference, they combine double compression seals with shielding plates or gaskets.
- Cable glands designed specifically to maintain a fire's ability to spread via cables are known as fire-resistant cable glands. To stop the spread of flames and smoke, they frequently have several compression seals and fire-resistant materials.
HOW TO FIX THE DOUBLE COMPRESSION CABLE GLAND?
To fix the double compression cable gland, follow these steps--
Disconnect the power supply: To avoid any electrical risks, make sure the power supply is off and unplugged before working on the cable gland.
The outer gland nut must be unscrewed in an anticlockwise manner in order to be detached from the gland body.
Carefully divide the gland body into two parts after the gland nut has been removed. The compression seal and cable will become visible as a result.
Verify the pressure seal's condition by looking for any indications of wear, corrosion, or issues with alignment. The seal must be changed with another one if it is worn out or damaged.
Adapt cable positioning: Make sure the cable is positioned correctly inside the gland body. It shouldn't be twisted but should be centered.
Reassemble the gland body by inserting the cable once more and making sure it is securely fastened. Align the gland body's two parts, then fasten them together.
Reattach the gland nut to the gland body and tighten it by turning it clockwise. To properly tighten it, use the proper tool. Avoid over-tightening as this could harm the cable or the gland.
Conduct a final inspection - Verify that the cable is kept in place securely and verify all connections one more time. Verify that the compression seal is properly positioned and that there are no gaps or alignment issues that can be seen.
Reconnect the power source and test the cable to make sure it is operating properly after you are certain that the gland has been fixed appropriately.
It is advised to ask a certified electrician or expert with knowledge of cable gland repair for help if you are unsure or uneasy about any of these procedures.
