Classification And Selection Methods Of Cable Drums

Classification and selection methods of cable drums

Cable reel is a device used to wind up and release cables. It is widely used in electric power, petroleum, chemical industry, port, steel, mining and other industries. Cable drums can protect cables from damage and extend the service life of cables, while also ensuring the stable operation of equipment and the safety of personnel. So, how to choose the right cable reel? This article will introduce the selection method of cable drum from the following aspects.

 

 

Classification of cable reels

 

Cable drums can be divided into different types according to different standards. Common classification standards are:

 

Drive form: According to the drive mode, it can be divided into two categories: non-electric and electric. Non-electric cable reels mainly rely on mechanical means such as springs, weights or magnetic couplings to achieve winding and release, and are suitable for small size, small stroke, and low speed applications. Electric cable reels mainly rely on electrical methods such as motors, frequency converters or hysteresis devices to achieve winding and releasing, and are suitable for large-sized, large-stroke, high-speed situations.

 

Position of the collector slip ring: Depending on whether the collector slip ring is installed inside or outside the drum, it can be divided into two types: internal slip ring type and external slip ring type. The cable drum with built-in slip ring has the advantages of compact structure, dustproof and waterproof, and easy maintenance, but it has certain requirements on the diameter of the drum. The slip ring external cable drum has the advantages of simple structure and unlimited drum diameter, but it has high environmental requirements and requires protection measures such as protective cover or explosion-proof box.

 

Winding material: Depending on whether the material wound on the drum is a cable or a hose, it can be divided into a cable drum and a hose drum. Cable reels are mainly used to transmit power or signals, and hose reels are mainly used to transmit fluids or gases.

 

Cable arrangement: Depending on whether the cables on the drum are single row or multiple rows, they can be divided into two types: axial single row and axial multi-row. Axial single row means that there is only one layer of cable on the drum, which is suitable for flat or small-sized cables. Axial multi-row refers to multiple layers of cables on the drum, which is suitable for round or large-sized cables.

 

 

Cable drum selection factors

 

When choosing a cable drum, you need to consider the following factors:

 

Cable type and gauge: Different cable types and gauges will affect the size and power requirements of the drum. For example, larger gauge cables may require larger drums and stronger driving force. Flat cables can only be used with axial single row drums. When selecting, the appropriate drum diameter and width should be determined based on the actual cable used.

 

Winding length: Winding length refers to the maximum stroke length that can be accommodated on the drum, which affects the size and power requirements of the drum. The longer the length, the higher the diameter and width requirements of the drum, and the higher the driving force requirements. When selecting, the appropriate drum size and driving method should be determined based on the actual stroke length used.

 

Equipment movement speed: Equipment movement speed refers to the moving speed of the equipment when winding and releasing cables, which affects the synchronization of the cable drum and the motor power. The faster the speed, the higher the synchronization requirements for the cable drum and the higher the motor power requirements. When selecting, the appropriate synchronous control method and motor power should be determined based on the actual moving speed.

 

Usage environment: The usage environment refers to the temperature, humidity, dust, corrosion and other conditions in which the cable drum is located, which affects the protection level and durability of the cable drum. The harsher the environment, the higher the protection level requirements for the cable drum, and the higher the durability requirements for materials and processes. When selecting, the appropriate protection level and material technology should be determined based on the actual environmental conditions of use.

 

Economy and maintenance: Economy and maintenance refer to the cost and maintenance difficulty of the cable drum during use, which affect the return on investment and service life of the cable drum. An efficient, durable and easy-to-maintain cable drum not only improves work efficiency, but also reduces operating costs and extends service life. The selection should be based on the actual cost budget and maintenance capabilities to determine the appropriate economy and maintenance.

 

Safety requirements: Safety requirements refer to the relevant regulations and standards that cable drums need to comply with during use, which affects the design and certification of cable drums. If the equipment is used in hazardous environments, such as petroleum, chemical and other industries, then you need to choose a cable drum with explosion-proof performance and pass the corresponding certification. The selection should be based on the safety requirements of actual use to determine appropriate design and certification.

 

In short, the cable reel is a practical device that can improve the efficiency and safety of cable use. When selecting a cable drum, it is necessary to comprehensively consider factors such as cable type and specification, winding length, equipment movement speed, use environment, safety requirements, economy and maintenance to select the appropriate cable drum type and parameters.
