What are the quality evaluation criteria for wire reels?

Today, the ONEREEL team will introduce how to judge the quality of plastic reels: plastic reels are a kind of packaging for winding groups. Due to the particularity of their use, there are not only strength, size requirements, but also weight requirements in terms of quality. Once the requirements are not met, there will be phenomena such as uneven winding, bursting, and cover removal, which will cause huge losses to the User Company or individual. Therefore, ONEREEL plastic reel manufacturers generally make plastic reels in accordance with national quality regulations.

When the customer uses the plastic reel, the rotation speed is high, and the tension on the side plate is relatively large. Judging from the working conditions of the reel, a qualified reel must meet the following quality requirements for plastic reels:

(1) With the increase of the thickness of the wound copper wire, the force on the two sides of the reel continues to increase. In order to prevent the reel from being deformed and bursting, the reel is required to have a certain strength and rigidity;

(2) In order to ensure uniform winding, the concentricity of the coil should be within 0.10mm;

(3) Since the weight of the copper wire at the time of delivery is calculated by deducting the weight of the package after weighing, the weight tolerance requirements for the wire reel are very high. For example, the weight of the PC10 wire reel is required to be controlled at 500±2g, and the weight of the PT90 wire reel It is required to be controlled at 3900+30g;

(4) In order to reduce costs, the user unit requires the reel to be recycled repeatedly.

Spools are not allowed to be loaded horizontally. Lying flat will loosen the winding of the cable and easily damage the cable and the cable reel. Power cables are generally wound on cable drums for transportation, storage and laying.

The short section of cable below 30m can also be rolled into a circle according to the small bending radius not less than the allowable cable, and it should be transported after being tied up at least four places. In the past, the cable reels for mining cables were mostly wooden structures, but now they are mostly steel structures, because the steel structure is relatively strong and not easy to damage, which is very good for protecting the cables, and this kind of cable reel can be reused, which is more economical than wooden cable reels .
