كابل الغدة | Types and Sizes of Cable Glands | Why we using cable glands? How many types of cable glands we use in the electrical industrial areas. What are the sizes of cable glands used in the electrical construction?
Cable gland is designed to permit the entry of cable in to electrical equipment or component which provide earthing, أساس, bonding, عازلة, sealing, retention and strain relief. It provides mechanical supports for cables. Glanding and termination is an important work in the electrical construction. There are various types of glands are used in the oil and gas areas. Mostly using cable glands are single and double compression cable glands.
We should have to use proof types of glands such as flame-proof, explosive proof in case any abnormal situation. In small type of industries, we should have to use single compression cable glands. We commonly use double compression cable glands in the plant and large size construction areas. Part names of single compression cable glands are check nut, gland body, washer, ring and compression nut. Part names of double compression glands are gland base, entry body , ring, cone and washer.
TYPES OF CABLE GLANDS : SINGLE AND DOUBLE COMPRESSION CABLE GLAND
There are four types of cable glands are used in the electrical construction. Single compression gland should be used in the small type industries. Double compression glands should be used in the plant. Flexible hose glands are used in the heat areas. Pvc glands are used for the control cables.
Purpose of use – Mechanical support and earthing.
Parts name – Body, washer, nut, ring and cone.
The four type of glands, classified by construction method. These are,
1. Single compression
2. Double compression
3. Flexible hose
SINGLE COMPRESSION CABLE GLAND
This type of cable glands are commonly used in buildings and small industries. We should use single compression gland for the flat armoured cables.
There are three types of single compression glands available in electrical industries. They are,
1. Single compression light duty
2. Single compression weather proof
3. Single compression flameproof
DOUBLE COMPRESSION CABLE GLAND
In power plant and oil and gas plants, we use double compression. We should use double compression gland for the round armoured cables.
Three types of double compression glands are used in electrical industries. They are,
1. Double compression light duty
2. Double compression weatherproof
3. Double compression flameproof
CORRECT SELECTION OF GLAND
Cable gland should be selected on following factors
1. Type of cable (Armoured and Unarmoured).
2. Size of gland.
3. Entry permit type or thread description.
4. Circumstance (Normal or abnormal situation).
5. Manufactured material
6 TYPES OF CABLE GLAND
There are 6 types of glands are used in the construction field. They are,
1. Brass indoor type gland
2. Brass outdoor type gland
3. Brass straightening unarmoured gland
4. Brass weatherproof
5. PG threaded gland
6. Industrial gland
Brass Indoor Type Gland
The gland is good handling in use with different types of cable whether plastic, rubber, metal or any other. This type of glands are used in dry indoor areas and used with all type of single wire armoured cables, plastic or rubber sheathed cables. Brass indoor gland suitable for single wire armored, plastic or rubber sheathed cable. We should have to use shroud for ingress protection. We use this type for SWA armoured cables.
Brass Outdoor Type Gland
This type is made by high quality material for use in outdoor purpose with different types of cables sheathed or unsheathed. Brass indoor and outdoor glands commonly used with single wire armored(SWA). Plastic or rubber or metal sheathed cable. Terminates and secure cable armoring and outer seal grips sheath of cable thus ensuring mechanical support and earthing. Use shroud for additional protection.
Application : Outdoor or indoor, for use with all type of single wire armoured cables, plastic or rubber sheathed cable. Popularly used for SWA, plastic of rubber sheathed cables. Used in dry indoor conditions. This type cable gland sizes are 20, 25, 32, 40, 50, 63, 75 75 مم (S , L and M) Additional materials: earth tag, pvc shroud, rubber, washer, brass lock nut. Cable type: wire braid armour.
Brass Straitening Unarmoured Gland
This type of glands are used for different type of unarmored or rubber sheathed cables. Brass indoor and outdoor gland suitable for all types of unarmored cables, plastic or rubber sheathed cables.
تطبيقات: Used for unarmored and plastic insulated cables. Indoor & Outdoor wherever it is required to provide sealing on cable outer sheath. Various sizes are 20, 25, 32, 40, 50, 63, 75 75 مم (S , L and M). Additional materials: earth tag, pvc shroud, rubber, washer, brass lock nut. Cable Type: wire braid armour.
Brass Weatherproof Gland
This type cable gland is used precisely with armored different types of swa cables whether plastic or rubber sheathed ones. This type gland is known for its uninterrupted services once the gland is fixed to the cables. This is suitable for single wire armour or rubber sheathed cables.Outer seal grips bedding layer of cable for use in most climatic situations. Manufactured in various proof type like weatherproof andwaterproof. It has a separate armour lock rings.
Application: In Outdoor or indoor, for use with single armored, all type of SWA cable, plastic or rubber sheathed cable. It is also available inweatherproof and waterproof. Inner and outer sheath. Cable type : Steel Wire Armour(SWA). Various sizes are 20, 25, 32, 40, 50, 63, 75 75 مم (S , L and M)
