When working with electrical installations, it is very important to select the correct cable gland for safety, efficiency, and reliability. Cable Gland Size Chart provides an essential guide to size selection based on cable dimension and type. This paper will provide you with the details of cable gland size, how to use the size chart, and why proper selection matters. Cable Glands are vital components in managing cables across industries. They ensure secure cable connections, protect against environmental factors, and maintain system integrity. Whether you’re an engineer or a technician, referring to a Cable Gland Size Chart is the first step toward making informed decisions.
What Is A Cable Gland Size Chart?
A cable gland is known as a cable connector. This device serves to secure and end cables in electrical equipment. The glands of cable prevent external influences of moisture, dust, or vibrations from affecting the functioning of the cable.
Principal Characteristics of Cable Glands:
- It provides an assurance for the grip on the cable.
- Protect from external hazards.
- Ensure electric safety and compliance.
- Offer for any cable type and sizes.
A Cable Gland Size Chart identifies the gland size suitable for use with the cable and its diameter and insulation. The correct gland size prevents both over-tightening and excessive gap that can undermine safety during installation.
How to Apply the Cable Gland Size Chart
- Measure Cable Diameter: Take a correct measure of the outer cable diameter.
- Cross-Check Chart: Find the matching gland size with the chart on the diameter of your cable.
- Consider the Type of Cable: There are different types of cables (armoured, unarmoured) that have specific gland types.
- IP Ratings: Make sure that the gland’s ingress protection rating is in line with your application.
Cable Gland Selection Factors
1. Cable Type
- For armoured cables, additional layers of protection need a gland that is specifically designed for this.
- For non-armoured cables, standard glands are preferred for secure termination.
2. Material
- Brass Cable Glands: Durable and corrosion-resistant.
- Plastic Cable Glands: Light in weight and inexpensive for non-industrial applications.
- Stainless Steel Glands: Suitable for harsh environments where maximum protection is required.
3. IP Ratings
- IP ratings of Ingress Protection define the dust and water resistance of the gland. Glands rated IP67 or IP68 are suitable for outdoor and industrial applications.
4. Temperature Range
- Select glands suitable for the temperature range of your installation.
5. Certifications
- The gland must be compatible with industry standards such as ATEX or IEC for hazardous environments.
