Engineering design of electrical systems requires careful selection of cable entry components. A Metal Cable Gland is often chosen for applications requiring high mechanical strength and environmental sealing.

Design specifications typically include thread size (M16 to M63), cable range (3 mm to 44 mm), and sealing class (IP66–IP68). Engineers must match these parameters with cable type and enclosure requirements.

Material selection is based on environmental exposure. For example:

Brass: general industrial use

Stainless steel 316: marine and chemical environments

Nickel-plated brass: enhanced corrosion resistance

Temperature rating is another key parameter. Standard Metal Cable Glands operate between -40°C and +100°C, while high-temperature variants can withstand up to +120°C or more depending on sealing material.

Compression structure design ensures uniform pressure distribution across the cable sheath. This prevents insulation damage while maintaining a watertight seal.

Electrical conductivity is also considered in armored cable applications. The gland body ensures low-resistance grounding paths, often below 0.1 ohm resistance under test conditions.

These design features make Metal Cable Glands suitable for power distribution units, automation systems, and industrial control networks where reliability is critical.
