Electrical Glands – Types, Functions & Industrial Applications

Introduction
In every industrial or commercial electrical setup, safety, durability, and proper cable management are critical. One essential component that ensures secure and sealed cable entry into enclosures is the electrical gland. Whether used in power plants, automation units, marine environments, or hazardous zones, electrical glands provide strain relief, protection, and grounding for various cable types.

This article explores the key types, applications, and advantages of electrical glands, helping you make informed decisions for your next installation.

 What Are Electrical Glands?
Electrical glands, also known as cable glands, are mechanical fittings designed to securely terminate and seal the end of electrical cables entering panels, junction boxes, and enclosures. They serve multiple purposes — from protecting cables against mechanical stress to ensuring environmental sealing and electrical continuity in armoured cables.

Electrical glands are available in a range of sizes, materials, and specifications to suit different cable types and operational environments.

 Types of Electrical Glands
Here are the most common types of electrical glands used in industrial and commercial applications:

Single Compression Glands:
Ideal for unarmoured cables, offering basic sealing and strain relief.
Double Compression Glands:
Designed for armoured cables; they provide extra sealing on both the inner and outer sheath for enhanced safety.
Weatherproof Glands (IP Rated):
Used in outdoor applications to protect against dust, water, and UV exposure.
Flameproof (Exd) Glands:
Engineered for use in hazardous zones like oil & gas, where flame and explosion protection is critical.
EMC Glands:
Provide electromagnetic compatibility, preventing signal interference in sensitive installations.
Nylon or Plastic Glands:
Lightweight and corrosion-resistant; ideal for non-metallic cable requirements.
 
Key Benefits of Electrical Glands

Strain Relief: Prevents cable pull-out and reduces wear on connected devices.
Sealing Protection: Maintains ingress protection (IP) against dust, water, and other contaminants.
Electrical Continuity: Ensures proper grounding of cable armour in metallic glands.
Durability: Withstands tough industrial environments, vibration, and extreme temperatures.
Compliance: Meets global standards such as IEC, ATEX, UL, and IS codes.

 
Applications of Electrical Glands
Power generation and transmission units
Manufacturing and automation plants
Oil & gas and petrochemical facilities
Data centers and communication systems
Marine, offshore, and renewable energy setups
Hazardous area electrical installations

Proper selection and installation of electrical glands ensure reliable, safe, and long-lasting performance of the electrical system.
