The rapid growth of EV charging stations across India and worldwide has increased the demand for reliable electrical infrastructure. One small but critical component in every charging system is the cable gland. Whether engineers are selecting a brass cable gland, checking a cable gland size chart, reviewing cable gland sizes, or matching the correct cable size and gland size chart, proper cable termination is essential for safety, durability, and performance in EV charging equipment.
In modern EV charging infrastructure, correct cable management ensures protection against dust, moisture, vibration, and environmental exposure. Installers working with armoured cable gland size chart PDF, electrical cable gland size chart PDF, or selecting between single compression cable gland and double compression cable gland must ensure compatibility between the cable type, gland size, and charger enclosure. Using the right industrial cable glands prevents cable damage, improves sealing, and increases the lifespan of EV charging stations.
When it comes to electrical safety and industrial wiring, one component that often goes unnoticed but plays a critical role is the cable gland. Many engineers and buyers still ask, “What is cable gland and why is it so important?”
A cable gland sometimes referred to as cable glands, cable and gland, or even cable glandes in certain regions acts as a sealing and securing device for cables. From waterproof cable gland solutions that protect against moisture, to brass cable gland connectors that deliver durability in hazardous areas, these small components are essential for keeping electrical systems safe, compliant, and long-lasting.
Types of Cable Glands Used in EV Charging Infrastructure
Different EV charger installations require different cable gland types depending on cable structure, environmental conditions, and power requirements. Selecting the correct cable gland improves sealing, mechanical strength, and electrical reliability in EV charging systems.
Brass Cable Glands
Brass cable glands are widely used in EV charging infrastructure because of their high durability, corrosion resistance, and long operational life. They are commonly installed in EV charger panels, distribution boards, and industrial electrical enclosures where reliable cable sealing is essential.
Single Compression Cable Glands
Single compression cable glands are designed primarily for unarmoured cables and provide an efficient sealing mechanism at the cable sheath. They are often used in indoor EV charger installations and electrical panels where environmental exposure is limited.
Double Compression Cable Glands
Double compression cable glands offer enhanced sealing and cable retention by compressing both the cable armour and inner sheath. These glands are recommended for armoured cables and outdoor EV charging stations where vibration and environmental exposure are higher.
Armoured Cable Glands
High-power EV fast chargers often use heavy armoured power cables. In such cases, installers refer to an armoured cable gland size chart or armoured cable gland size chart PDF to select the correct gland based on cable diameter and armour construction.
Typical Cable Gland Size Reference
Engineers frequently rely on a cable gland size chart or gland chart during installation planning to ensure the correct gland size is selected for EV charging cables.
| Cable Size | Typical Gland Size | Application |
|---|---|---|
| 10–16 mm | M20 | Small EV chargers |
| 16–25 mm | M25 | Medium AC chargers |
| 25–38 mm | M32 | DC fast chargers |
| 38–50 mm | M40 | High power charging units |
Installation Best Practices for EV Charger Cable Glanding
To ensure reliable EV charging infrastructure, installers should follow industry best practices for cable gland selection, sealing, and safety compliance.
Use Correct Cable Gland Size
Always verify the cable diameter using a cable gland size chart PDF before installation. Selecting the correct gland size ensures proper cable grip, sealing, and long-term reliability in EV charging systems.
Ensure Proper Sealing
Tighten the gland correctly to achieve full environmental sealing. Proper installation protects internal EV charger electronics from dust, moisture, and harsh outdoor conditions.
Use Certified Industrial Cable Glands
Choose cable glands that meet industrial safety certifications such as:
- IP Rated Protection
- RoHS Compliance
- Industrial Electrical Safety Standards
Avoid Incorrect Gland Selection
Using the wrong gland size chart or incorrect cable gland can lead to serious issues such as:
- Water ingress
- Cable insulation damage
- Electrical faults
- EV charger downtime
Future of EV Charging Infrastructure
As EV charging stations continue to expand across highways, residential complexes, and commercial parking areas, the demand for reliable cable management components is growing rapidly.
Selecting the correct cable gland size is essential for maintaining secure cable entry and ensuring safe electrical connections within EV charging systems.
Installers must rely on reliable armoured cable gland selection to protect high-power charging cables used in fast and ultra-fast EV chargers.
Using durable industrial cable glands helps ensure long-term performance in outdoor charging stations exposed to dust, rain, and harsh weather conditions.
Following safe electrical installation practices improves charger reliability, reduces maintenance issues, and enhances electrical safety.
Even though cable glands are small components, they play a major role in electrical safety, charger reliability, and long-term system performance.

FAQs
What cable glands are used in EV charging stations?
EV charging stations commonly use brass cable glands, single compression cable glands, and double compression cable glands depending on the cable type and installation environment.
How do I choose the correct cable gland size?
You should measure the cable diameter and refer to a cable gland size chart in mm or cable gland size chart PDF provided by the manufacturer.
Are armoured cable glands required for EV chargers?
Yes, armoured cable glands are often used in high-power EV chargers where armoured cables are required for extra protection.
Why is a cable gland size chart important?
A gland size chart ensures the cable fits properly inside the gland, preventing water ingress, vibration damage, and electrical faults.
What IP rating should cable glands have for EV charging stations?
Outdoor EV charging stations typically require cable glands with IP66, IP67, or IP68 protection.
What is the difference between single and double compression cable glands?
Single compression glands seal the outer sheath of the cable, while double compression cable glands provide additional sealing and armour clamping, making them ideal for heavy-duty applications.
