How to select wire reel or cable spool?

November 15, 2022

Wire reel or Cable Spool is a wire reel or cable spool that provides winding wire and cable functions for industrial and mining enterprises. At present, it is widely used in many industries, such as oil fields and mines, building construction, machinery manufacturing units, scientific research units, ports and docks, shopping malls, hotels, road and bridge construction, etc. With the increasing diversification of industrial demand, mobile wire reel or cable spool has become a new favorite in the Cable Reel market, which not only improves the production environment, but also improves the production efficiency.

One of the selection criteria for wire reel or cable spool - super resistance to external forces

Wire reel or cable spool is greatly affected by external force factors such as environment, so external force resistance (and cable reel material) is an important standard to measure a wire reel or cable spool.

1. It is protected against rain, dust and splash.

2. High temperature blocking safety device is provided. The cable reel shall be equipped with an overheating overload protector, an electromagnetic leakage protector and double fuses. When the temperature of the cable reel is too high, the power will be cut off automatically to protect the cable reel from fire. Especially in the hot summer, after the "washing" of high temperature and rain, unqualified cables are very prone to spontaneous combustion and electric leakage, which is extremely dangerous.

The second selection standard of wire reel or cable spool - "prevention in advance" safety setting. High quality products are like leaders. They should not only have the ability to deal with emergencies, but also have the awareness of "prevention in advance".

The wire reel or cable spool shall be equipped with special fixed line clamp, locking function, all steel shield and other humanized safety devices, which can not only facilitate construction operation, but also nip potential safety hazards in the cradle.

The third selection standard of wire reel or cable spool - complete types

There are many applications of wire reel or cable spool. The cable reel with different purposes has different requirements for various indicators of the cable reel. For example, high insulation and high temperature resistance cable reel is required in high temperature places; Explosion proof cable reel is required in the environment with low safety factor; Different types of cable reels, such as tripod, trolley and wheel car, may be required for different working places.

Compared with turnkey cables, phase segregated cables are more expensive, but have the following advantages:

1. The electric field around the cable core is uniform, and there is no tangential stress on the insulation surface. Compared with the turnkey cable, the insulation function is better, so it can be applied to the cable with 35kv voltage level.

2. There is no impregnated filler inside the lead (aluminum) package, so the insulating oil is not easy to move, which can reduce the appearance of oil leakage during operation.

3. The impregnation of paper insulation is simple and full, which is easy to ensure the production quality.

4. The heat dissipation condition is good and the current carrying capacity can be improved.

5 The deformation is small in case of twists and turns, and the internal insulation is not easy to be damaged.

6. When single-phase fault occurs, it can be repaired alone, which reduces the repair cost and shortens the repair time
