Characteristics, Selection, and Application of Metal Cable Gland PG Type

In industrial electrical wiring, sealing protection and firm fixation of cable interfaces are key to ensuring the long-term stable operation of electrical equipment. Metal cable gland PG type, with its solid structural design and strong environment adaptation capability, can effectively improve common problems such as water ingress, dust accumulation, loosening, and corrosion. It is a commonly used standardized accessory in industrial wiring systems.

The main fastening structure of the metal cable gland PG type is made of nickel-plated brass, which is vibration-resistant, oil-resistant, and not easily deformed, suitable for most conventional industrial scenarios. For corrosive environments such as salt spray, acid, and alkali, 304 and 316 stainless steel materials can be selected to significantly improve overall corrosion resistance. Internal clamping parts are made of UL-certified PA66 nylon, meeting the UL94V-2 flame retardant standard, with good insulation and resistance to aging and cracking, ensuring safe and stable use.

The metal cable gland PG type has excellent temperature adaptation capability, with a regular static working temperature range of -40°C to 100°C, and instantaneous heat resistance up to 120°C, meeting the continuous operation needs of daily industrial equipment. For low temperature, high temperature chemical, and special corrosion scenarios, modified sealing accessories can be customized to achieve stable operation from -60°C to 220°C, adapting to the wiring protection needs of new energy, chemical, and outdoor heavy industry scenarios.

The metal cable gland PG type adopts a special integrated design of clamping claws and clamping rings, with a wide clamping range, suitable for most conventional sheathed cables. With structural support, the product has excellent tensile performance, which can effectively prevent cable slipping caused by equipment vibration and external pulling. At the same time, it has strong protection capabilities, being waterproof, dustproof, salt spray resistant, and resistant to weak acids, alcohol, industrial oil, grease, and conventional solvents, adapting to various complex industrial production scenarios.

The metal cable gland PG type has strong versatility and is suitable for electrical wiring in multiple industries. It is widely used in industrial automation control cabinets, servo equipment, sensor circuits, machine tool equipment, new energy electrical systems, building automation, and fire electrical equipment, providing long-term sealing protection and firm fixation for cable entry ports of various equipment.

FAQ

1.What is the correct basis for selecting PG type cable glands?

Answer: PG type cable glands are selected based only on the outer diameter of the cable's outer sheath. A caliper should be used to measure the outer diameter at the thickest part of the cable sheath, taking the maximum value from multiple measurements and leaving a margin for cable production tolerances and deformation under working conditions. Do not refer to the cable conductor cross-section.

2.Can PG thread connectors be mixed with metric threads for assembly?

Answer: No. The tooth type and parameters of PG threads and metric threads are completely different. Forcing assembly will cause thread stripping and locking failure, directly damaging the sealing structure and losing waterproof and dustproof protection performance.

3.How to ensure PG glands do not loosen on high-frequency vibration equipment?

Answer: Relying on the composite clamping structure to uniformly lock the cable, combined with the anti-vibration rigidity of the metal body, and with standardized installation and reasonable cable margin, common risks such as cable loosening, water seepage, and falling off caused by high-frequency vibration can be effectively avoided.

Conclusion

Metal cable gland PG type, with its reliable materials, scientific locking structure, and multi-directional protection capabilities, is suitable for various conventional and harsh industrial wiring scenarios. It can stably ensure the tight sealing of cable interfaces, effectively reduce the probability of circuit faults and equipment maintenance costs, and provide reliable guarantees for the long-term safe operation of industrial electrical equipment.
