Type of Cable.
Gland Size.
Entry Type/Thread Specification of application.

Unarmored: Unarmored Cable will require outer seal within Gland to not only Provide ingress protection but also degree of retention.

Armored: Gland that required clamping mechanism to terminate the armored both mechanically and electrically.

WHAT IS DIFFERENCE BETWEEN SINGLE COMRESSION AND DOUBLE COMPRESSION GLANDS?

Anish Electricals is the foremost manufacturer, supplier, Traders & stockiest of cable gland in Kolkata, West Bengal.

Double compression glands provide extra support to the heavy armored cables entering or exiting the panel while Single compression glands are used for light armored cables.

Normal Cable Gland is also called Single Compression Cable Gland. As the name suggests, while you tighten the Gland, the grip or compression is effected only at one p [lace (i.e.) at the cable armour only. There is scope for moisture and corrosive vapors to enter the gland and thus into the cable.

Whereas in Double-Compression Gland, the compression happens both at the cable armour as well as at the inner sheath. This is sort of two sealing. Hence, chances of moisture or vapors entry are minimized. Hence these glands are also known as Weather-proof cable glands or Flame-proof cable- glands.
