How to choose the suitable cable reel? | Conductor-stranding process

.
Cable conductor or wirerope consist of several single metal wires or strands of metal wire laid (twisted) into a helix. This structure is stable and flexible.
The conductor is normally made by stranding machine, for example twist buncher machine, Tubular Stranding Machine, Fork Stranding machine, Rigid Frame Stranding Machine, Cage Stranding machine.
In this article, we will choose the most suitable cable reels for the various stranding machines.

1.    The reels for twist buncher machine

The twist buncher machine can produce the LAN cable, flexible and rigid copper wire, power wire.

The plastic reels is common, but now more and more factories choose small steel flat steel reels or pressed steel reels. And for the large twist buncher machine, the take-up bobbins are industrial metal drums, which are more durable and cheaper.

 2.    The reels for tubular stranding machine

The tubular stranding machine can produce steel stranded wire, aluminium stranded wire, and control cable.

The curly edge and stiffeningribs reels are the most common pay-off reels for this machine. The pressed bobbins are made from steel plate, the flange is pressed to bars and machined to beaded edges, both of which increase the strength of the reels.

If you produce the steel stranded wire, the steel plate steel reels may be the best choice. The flanges are thick steel plate and the drum is thick-wall steel pipe. Which can stand the tight pressure of the steel wires.

3.    The reels for fork stranding machine

The fork stranding machine is very common machine in the cable and wire industry. It can produce Cu, Al wire, ACSR, compacting the sector conductors.

The double wall high speed steel reels and pressed steel reels are the most two kinds of process reels for this machine.

The double wall bobbins are drum-turned and dynamically balanced process reels. They run smoothly and very concentric in high rotation rate. These stranding reels are suitable for high speed stranding machine.

4.    The reels for rigid frame stranding machine

The rigid frame stranding machine is the most common stranding machine in cable and wire industry. It has much stronger structure and higher running speed. It is better to use dynamicallybalanced reels, such as, double-skin flange steel reel, which is heavy duty process reel with double-skin flanges and curly edge.

While, if the stranding machine is not high-speed machine, the single flange pressed steel reel can be used.

5.     The reels for cage stranding machine

Reel with single wall rimmed flange in pressed steel is the most commonly used for this type stranding machine.

For the record, this article is a brief introduction, you'd better to choose the cable reels according to actual situation. If you want to know any more, please access to our website: www.nriss.com

How to choose the suitable cable reel for wire-pulling process

Cable reels are widely used in the electric cables, fiber optic cables and metal wire products. From the wire-pulling process to the wire-stranding process, from the enameled wire production line to the EHV cable production line, you will find the various cable and wire reels. Normally the cable and wire reels are made from wood, plywood, plastic and steel. But how to choose the proper reels for your machine? This article attempts from the wire-pulling process latitude to discuss how to do this job well.

Rod breakdown machine is necessary for this process. Because of powerful pulling force  and high temperature of wire, the pulling tools for rod breakdown machine are normal very strong. The enhanced steel spools are the best choice. The enhanced steel spools are made from very thick steel plate and thick-walled seamless steel pipe. Often the spools equipped with roll edge, reinforced ring, reinforcing bars, or enhanced drum. The spools are very strong for wirepulling process. By the way, if the wire is high temperature, you should let the steel steels and spools manufactory to know that, which is very important. Click here for more information.

As the wire diameter becomes more and more small, you should choose the high-speed flat steel reels. For example metallic, enamelled and capillary metallic wires, you'd better choose the high-speed flat steel reels. The steel reels are turned all over, and dynamically balanced for speeds up to 50 m/s. The fully turned flange steel reels are normally according the DIN 46397 or the your requirements. You should provide the clamping device technical parameter, the manufactory will produce the reels for you. Click here for more information.

If your products are those metallic, enamelled and capillary metallic wires, now you should drawing them on the delivery reels. This reels normally are plastic reels, according to the loading capacity, the manufactory will provide you the most economic plastic reels.

If your products are steel wire like silicon cutting wire and tire-cord wire, you should choose the radial tires steel spools and cutting-wire steel spools. Clickhere for more information.

In this article we talked about the wire-pulling processtools. We hope that will help you. In next article we will provide our experience about the stranding process.

Why should you choose steel reels rather than wooden or plastic reels?

Reels are one of the wire pulling tools in the cable and wire industry. Cable reels, drums and spools usually come in four different types: wood, plywood, plastic and steel.

Nowadays more and more factories choose the metal reel instead of orthodox wooden reel. And why that?

Here are 9 metal reel advantages why people prefer.

1.     The steel reels/drums are manufactured in an eco-friendly manner.

They are made of steel, and fully recyclable. They will not damage the environment.

2.     Steel structure is strong shock resistance ability. So it is much safer to use the steel reels/drums for the delivery.

3.     It is possible to make different size steel reels according to customer specifications. Reinforcementsflange and drum are available.

4.     Steels reels are used widely, in the cable and wire industry. From the production of bare copper and aluminum wire, to production of the extruding PVC, PE or XLPE cable.

5.     The life of a industrial metal drum is much longer than the wooden or plastic ones. They can be used repeatedly. They are really durability steel spool. The overheads for the purchaser/user decrease as compared to those for the user of wooden drums

6.     These steel reels are not as easily stolen.

7.     They can be used for annealing process. The enhanced welding-type structure, can stand the high temperature. The wooden and plastic reels are not able to do this.

8.     They can be used for wire drawing process. The flat-plant type steel reel, and double wall high speed reels are dynamically balanced reels. They can be used for enameled wire, capillary wire and metallic wire.

9.     The steel corrugated Drums for delivery can be made as knocked-down corrugated reel, which will reduce purchasing cost.
