Its performance directly affects the quality and production efficiency of wires and cables. With the continuous advancement of materials science and manufacturing processes, plastic cable drums have been increasingly refined in design and functionality to meet the demands of various fields. ​

The structural composition of plastic cable drums

Side panels

The side panels are an important component of plastic cable drums and are usually located on both sides of the reels. It serves to support and protect the cables, preventing them from scattering or getting damaged during winding and transportation. The diameter of the side plate directly affects the winding capacity of the cable reel. A larger diameter of the side plate can accommodate longer cables. The material is generally made of high-strength plastics such as ABS and PP, which have good impact resistance and corrosion resistance, ensuring that the side panels can work stably in various environments. For instance, at some outdoor construction sites, cable reels need to withstand wind, sun and rain erosion. The side panels made of ABS material can effectively resist these harsh environmental factors, ensuring the service life of the cable reels.

(1) Cylinder

The cylinder is the middle part connecting the two side plates, and the cable is wound around the cylinder. The diameter and length of the cylinder determine the winding space and shape of the cable reel. It needs to have sufficient strength and stability to withstand the weight of the cable and the tension generated during winding. The surface of the cylinder is usually designed to be relatively smooth to reduce the friction of the cable during winding and laying, and to avoid damaging the outer sheath of the cable. Some high-end plastic cable drum bodies also adopt special processing techniques, such as adding anti-slip textures to further enhance the stability of cable winding and prevent cables from sliding on the body. ​

(3) Shaft hole

The shaft hole is located at the center of the cable reel and is used to connect with the laying equipment or transportation tools. The size and accuracy of the shaft hole are of vital importance. It must fit closely with the shaft of the matching equipment to ensure that the cable reel can rotate smoothly during the wire laying process without any shaking or eccentricity. In power engineering, the shaft holes of large cable reels are usually specially reinforced. Metal inserts or thickened plastic are used to enhance the load-bearing capacity and wear resistance of the shaft holes, so as to meet the long-term and high-load working requirements. ​

How to choose the right plastic cable drum

(1) Select according to the cable specification

Cable diameter: The diameter of the cable is one of the important bases for choosing a cable reel. The diameters of the cable reel's cylinder and side plates should be large enough to ensure that the cables can be tightly and neatly wound around the reel, and that winding difficulties or deformation of the reel will not occur due to overly large cable diameters. For thicker cables, cable reels with larger cylinder diameters need to be selected. For thin cables, cable reels with relatively smaller cylinder diameters can be selected to improve space utilization. ​

Cable length: Select a cable reel with an appropriate winding capacity based on the length of the cable to be wound. The winding capacity of a cable reel is usually determined by the diameter of the side plates and the length of the cylinder. When calculating the winding capacity, the outer diameter of the cable and the number of winding layers need to be taken into consideration. Generally speaking, the larger the diameter of the side plate and the longer the length of the cylinder, the greater the winding capacity of the cable reel. In actual engineering, the specifications of cable reels should be reasonably selected based on the specific length requirements of the cables to avoid the need to replace cable reels multiple times due to insufficient winding capacity, which may affect work efficiency. ​

(2) Consider the usage environment

Outdoor environment: If the cable reel is to be used outdoors, its weather resistance and UV resistance need to be taken into consideration. Choose plastic cable drums with sun protection, water resistance and anti-aging functions to ensure that they can be used stably for a long time under harsh outdoor conditions such as direct sunlight and rain erosion, without deformation, fading or material aging. In salt spray environments such as by the seaside, it is also necessary to choose cable reels with stronger corrosion resistance. ​
Indoor environment: When used indoors, although the environmental conditions are relatively good, the coordination between the cable reel and the surrounding environment as well as the space occupation still need to be considered. For some places with high aesthetic requirements, such as shopping malls and office buildings, for interior decoration wiring, plastic cable drums with simple appearances and harmonious colors can be chosen. At the same time, according to the size of the indoor space, choose a cable reel of the appropriate size to avoid taking up too much space due to the cable reel being too large and affecting the indoor layout. ​

(3) Pay attention to quality and brand

Material quality: High-quality plastic cable drums are usually made of high-strength and environmentally friendly plastic materials. When making a choice, you can observe the appearance of the cable reel to check for any defects such as bubbles, cracks or deformations. You can also learn about the brand and performance parameters of the plastic materials used in the cable reels, such as tensile strength, impact strength, corrosion resistance, etc. High-quality materials can ensure that cable reels have good physical properties and a long service life. ​

Brand reputation: Choosing plastic cable drums from well-known brands is often more reliable. Well-known brands usually have strict production process standards and quality control systems, which can ensure the stability and reliability of product quality. Meanwhile, the brand's products have also become more complete in terms of after-sales service, such as providing product warranties and technical support. In the market, one can learn about the reputation and credibility of different brands of plastic cable drums by consulting product reviews, industry experts or other users, and thus make a wiser choice. ​

Maintenance and care of plastic cable drums

Regular inspection

Visual inspection: Regularly conduct visual inspections on plastic cable drums to check if there are any cracks, damages or deformations on the side panels and cylinders. If minor cracks are found, they can be repaired in time using plastic welding tools. For severely damaged or deformed cable reels, they should be replaced in time to avoid safety accidents during use. Check whether there is any wear or damage to the shaft holes, traction holes and other parts of the cable reel. If there are any problems, repair or replace the relevant components in time. ​

Inspection of rotating parts: Inspect the rotating parts of the cable reel, such as shafts and bearings, to ensure they rotate smoothly without jamming or abnormal noise. Regularly add lubricating oil to the rotating parts to reduce friction and extend their service life. When adding lubricating oil, a lubricant suitable for the plastic material should be selected to avoid using lubricating oil that is corrosive to the plastic. ​

(2) Cleaning and maintenance

Surface cleaning: Regularly wipe the surface of the plastic cable drum with a clean damp cloth to remove dust, dirt and debris. For stubborn stains that are difficult to clean, a mild cleaner can be used for cleaning, but it is necessary to avoid using cleaners containing strong acids, strong alkalis and other corrosive components to prevent damage to the plastic surface. After cleaning, the cable reels should be dried promptly to prevent water residue from causing plastic aging or rusting (if there are metal parts). ​
Internal cleaning: The interior of the cable reel, especially the interior of the cylinder, should also be cleaned regularly. Compressed air or a vacuum cleaner can be used to thoroughly remove the dust and debris inside to prevent these impurities from causing damage to the cables during the winding process. When cleaning the interior, it is necessary to pay attention to checking whether there are any foreign objects stuck between the cylinder or rotating parts. If so, they should be cleared in time.

(3) Store correctly

Storage environment: plastic cable drums should be stored in a dry, well-ventilated and cool place, avoiding direct sunlight and high-temperature environments. When exposed to sunlight or high-temperature environments for a long time, plastics are prone to aging and deformation, reducing their performance and service life. At the same time, avoid storing the cable reels in damp places to prevent the plastic from getting damp and moldy or the metal parts from rusting. ​

Storage method: Cable reels should be placed vertically to avoid horizontal stacking. Vertical placement can reduce the force on the side plates of the cable reel and the cylinder, preventing deformation due to long-term pressure. If stacking storage is required, it should be ensured that the number of stacking layers is not too large, and appropriate supports should be placed between each layer to disperse the pressure. During storage, it is necessary to avoid the cable reels being hit or squeezed by external forces to prevent damage. ​
