Introduction
In the world of electrical installations, ensuring robust and secure connections is paramount. One critical component that plays a significant role in this is the cable gland. This blog will delve into 4 core cable glands, highlight their key features, and provide an in-depth look at the SWA cable gland size chart to help you make informed decisions for your electrical projects.
What is a 4 Core Cable Gland?
A 4 core cable gland is an essential component used in electrical applications to secure and seal cables entering an enclosure. Designed specifically for cables with four conductors, they offer protection against environmental factors such as dust and moisture, making them suitable for both industrial and commercial installations.
Key Features of 4 Core Cable Glands
Protection
4 core cable glands provide a robust barrier against contaminants, ensuring that dirt, moisture, and other environmental elements do not compromise the integrity of the electrical system. This ensures longevity and reliability in demanding environments.
Strain Relief
These cable glands effectively manage mechanical stress on cables, preventing damage from bending, pulling, or other physical forces. This strain relief is crucial for maintaining the performance and safety of the electrical installation.
Ingress Protection Ratings
High ingress protection (IP) ratings, such as IP67 and IP68, are common in 4 core cable glands. These ratings indicate the glands’ ability to withstand water and dust exposure, ensuring their suitability for both indoor and outdoor applications.
Common Sizes and Specifications
4 core cable glands are available in various sizes to accommodate different cable diameters. Here are some typical specifications:
| Gland Size | Thread Size | Cable Diameter Range | Gland Length |
|---|---|---|---|
| 16mm | M25 | 10mm to 14mm | ~60mm |
| 95mm | M63 | 32mm to 48mm | ~85mm |
| 120mm | M90 | 50mm to 70mm | ~110mm |
| 150mm | M100 | 60mm to 80mm | ~120mm |
| 185mm | M125 | 80mm to 100mm | ~150mm |
These specifications ensure a secure fit around the cable, providing effective sealing and support necessary for reliable electrical connections.
Material Considerations
Selecting the right material for a 4 core cable gland is essential to ensure its suitability for the application environment. Common materials include:
- Plastic: Lightweight and corrosion-resistant, plastic glands are ideal for indoor use where environmental exposure is minimal.
- Brass/Nickel-Plated Brass: These materials offer durability and corrosion resistance, making them suitable for harsh environments. Nickel-plated brass provides an extra layer of protection against corrosion.
- Stainless Steel: Providing superior resistance to corrosion, stainless steel glands are perfect for industrial applications that demand high durability and protection.
