NPT Thread Coaxial Brass Cable Glands

Cable glands are key components in power systems and are used to provide reliable and safe connections between power cables. In the UK, cable glands are widely used in utilities, industry and commercial sectors. Understanding the types, sizes and international customs classifications of cable glands is essential for importers, exporters and engineers.

UK Cable Gland Types

Cable glands in the UK are usually classified according to voltage level and installation method.

• Low Voltage (LV) Cable Gland (up to 1KV)
Commonly used in home and commercial networks, including heat shrink, cold shrink and resin types.

• Medium Voltage (MV) Cable Gland (1KV-36KV)
Used in industrial and utility applications, these glands usually use heat shrink or preformed slip-on technology.

• High Voltage Cable Gland (above 36KV)
These are dedicated products for high voltage transmission systems and are usually customized and tested to specific standards.

• Heat Shrink Gland
Made of heat shrink tubing, it seals and insulates the connection. Widely used in low and medium voltage applications.

• Cold Shrink Fittings
Pre-expanded silicone rubber tubing that shrinks into place without the need for heat. Ideal for locations with limited access and environments susceptible to moisture.

• Resin Cast Fittings
Filled with a two-component resin compound, providing strong mechanical and moisture protection. Ideal for underground installation.

Sizes and Specifications for UK Cable Gland

The size of cable fittings in the UK is generally defined by the cable core size (cross-sectional area in mm²), the number of cores and the applicable voltage level. Some common examples include:

• Single core 25mm2 low voltage fitting.
• Three core 95mm2 low voltage heat shrink fitting.
• Three core 185mm2 medium voltage cold shrink fitting.
• Single core 630mm2 high voltage fitting.

Standards such as BS7888, BS EN50393 and IEC 60502 may govern their design and testing.

HS Codes (Customs Codes) for UK Cable Glands

In the international trade of cable fittings, Harmonized System (HS) codes are used to classify goods for customs clearance and tax purposes. In the UK and many countries, cable glands are often classified as:

• HS Code: 8547.20
Plastic insulating fittings for motors, appliances or apparatus. This category includes connectors, sleeves and similar articles used in wiring systems.

Other product details or material composition (such as resin content or metal parts) may slightly affect the classification. It is recommended to confirm the final HS code with the customs broker or refer to the UK trade tariff.

Understanding Cable Gland Manufactures in China:Types and Applications

China has become a global manufacturing hub for industrial components,including cable glands-a critical part of electrical and marine installations.In the article,we will explore Chinese cable gland manufactures,the types of cable glands produced,and the specialized field of marine cable sealing solutions.

1. China Cable Gland Manufactures:Global Competitiveness

Cable gland (also known as a cable connector or cable fitting)is a device designed to attach and secure the end of an electrical cable to equipment.Chinese manufactures have built a strong reputation for producing high-quality cable glands that meet international standards such as IEC,UL,and RoHS.

With advanced production facilities,China’s cable gland manufactures offer cost-effective solutions for various industries,including construction,oil&gas,renewable energy,telecommunications,and transportation.

2. Types of Cable Glands produced in China

Chinese supplies manufacture a wide range of cable glands,including:

▪Metal Cable Glands:Made of brass,stainless steel,or aluminum,suitable for harsh environments.

▪Plastic Cable Glands:Lightweight and corrosion-resistant,ideal for general-purpose applications.

▪Explosion-Proof Cable Glands:

Designed for use in hazardous areas(Atex or IECEx certified).

▪Multi-hole Cable Glands:Allow multiple cables to pass through a single gland.

These products come in different thread types(Metric,PG,NPT,G)and sealing ranges to accommodate various cable sizes and applications.

3. China Marine Cable Gland Suppliers:Focus on Safety and Sealing

In the marine and shipbuilding industries, cable glands must meet even stricter requirements due to exposure the saltwater,vibrations,and fire risks,Chinese marine cable gland manufactures provide:

▪Waterproof and IP68-rated glands for deck and hull penetrations.

▪Flame-retardant and fire-resistant glands for engine rooms and control panels.

▪Cable transit sealing systems that prevent water,gas,or fire from spreading through cable entries.

These products are certified according to international maritime standards such as DNV,ABS,and CCS.

4. Why Choose Chinese Cable Gland Suppliers?

▪Competitive Pricing:Mass production and cost-efficient logistics.

▪Customization:OEM/ODM services tailored to project needs.

▪Certifications:Compliance with global safety and quality standards.

▪Fast Delivery:Short lead time and worldwide shipping support.

Conclusion

Whether you are sourcing standard cable glands or specialized marine sealing solutions,Chinese manufactures offer a wide selection with proven quality.By understanding the types and applications of cable glands,engineers and buyers can make better-informed decisions for safe and efficient cable management in all kinds of environments.

In today’s rapidly developing industrial world,the demand for safe,reliable,and durable electrical connections is higher than ever.One essential component that often goes unnoticed-but plays a critical role-is the cable gland(also known as cable connector).At Wenzhou Chuangda Connector.,Ltd.We specialize in manufacturing waterproof cable glands to ensure the highest protection and performance for your electrical system.

Why Are Cable Glands are important?

Here are some key reasons why cable glands are essential

1. Waterproof Protection

In harsh environments where moisture and water expose are concern,waterproof cable glands provide a tight seal to cable glands provide a tight seal to prevent water from entering electrical enclosures.This is crucial for preventing short circuits,corrosion,and damage to equipment.

2. Mechanical Strain Relief

Cables connected to machines and devices are often subjected to movement,vibration,water,or tension.A cable gland provide strain relief,ensuring that no endue force is transmitted to the internal terminals or connectors.

3. Dust and Dirt Resistance

For equipment used in dusty or outdoor environments,cable glands offer an effective barrier against dust and other contaminants.This helps maintain the internal integrity of sensitive electronics.

4. Fire and Explosion Safety

In hazardous areas such as petrochemical or mining industries,special cable glands can prevent the ignition of flammable gases or dust.They are part of explosion-proof systems that protect both personal and infrastructure.

5. Maintaining Electrical Performance

A loose or exposed cable can lead to signal loss,electromagnetic interference,or even electrical failure.Cable glands secure the cable and maintain consistent and stable electrical performance.

6. Compliance with Safety Standards

Using the right type of cable gland ensures compliance with international safety standards and industry regulations,helping avoid legal or operational risks.
