What Is a Stainless Steel Cable Gland?

Stainless steel cable gland are essential components used to securely attach and seal cables to electrical equipment. They protect cables from mechanical stress and environmental hazards such as moisture, dust, and chemical exposure. Unlike glands made from plastic or brass, stainless steel cable glands offer superior durability, corrosion resistance, and strength, making them ideal for harsh industrial and outdoor environments.

When you need reliability in tough conditions—whether that’s offshore oil rigs, chemical plants, or marine equipment—stainless steel cable glands are the go-to choice. Curious how they work and where exactly to use them? Let’s dive in.

What Is a Stainless Steel Cable Gland?

A stainless steel cable gland is a mechanical device designed to fix the end of a cable to an electrical apparatus, ensuring both strain relief and a tight seal. The gland prevents water, dust, and other foreign particles from entering the enclosure while providing a secure connection.

Key Advantages of Stainless Steel

  • Corrosion resistance: Stainless steel, especially grades like 316L, withstands rust and chemical attack.
  • Mechanical strength: Superior impact and tensile resistance compared to plastic or brass.
  • Longevity: Stands up to extreme temperatures and harsh environments.

Standards and Certifications for Stainless Steel Cable Glands

To ensure safety, quality, and compatibility, stainless steel cable gland PG36 must meet strict standards. Here are some key certifications:

  • EN 62444: European standard specifying installation and testing requirements.
  • UL514B / CSA C22.2 No 18.3: North American standards ensuring electrical safety.
  • IEC 60529 (IP Ratings): Defines protection levels against dust and water ingress. Stainless steel glands often achieve IP66 to IP68 ratings.
  • IEC 60079 & GB 3836: Certifications for explosion-proof applications in hazardous environments.

Structure and Sealing Technology

Stainless steel cable glands combine robust materials with precise engineering to protect cables effectively.

Core Components

  • Outer body: Typically stainless steel 316L, offering high corrosion resistance.
  • Sealing rings: Multiple layers including chloroprene or TPU seals provide water and dust tightness.
  • Lock nuts and washers: Secure mounting with added ingress protection.

Sealing and Protection Levels

These glands often boast:

  • IP66 to IP68 for dust-tight and water immersion resistance.
  • Multi-layer sealing ensuring performance under pressure.
  • Tension relief to prevent cable damage due to pulling or vibration.

FAQ

How do stainless steel cable glands ensure waterproofing?

Through multi-layer sealing with high-quality elastomer rings and tight mechanical fastening, they maintain IP66 to IP68 ratings, allowing protection even against water immersion.

What are common installation mistakes?

Using incorrect gland sizes, failing to tighten lock nuts properly, or ignoring environmental compatibility could compromise sealing and mechanical protection.

How to choose the correct size?

Measure the cable’s outer diameter and select a gland within the clamping range specified by the manufacturer.

What is the lifespan of stainless steel cable glands?

Under normal conditions, they last many years due to corrosion and mechanical resistance but should be inspected regularly in extreme environments.

Are stainless steel glands suitable for all environments?

They suit most harsh environments but may be over-specified or unnecessarily costly for indoor, dry, or non-corrosive settings.

How to identify explosion-proof glands?

Check for IEC certified markings and compliance documents confirming suitability for hazardous zones.
