Cable laying methods

1. Give A Brief Description Of The Plastic Cable Heat Shrinkage Sealing Method

Answer: The heat shrinkage method applies to medium and low voltage rubber and plastic wire and cable joints, and terminal seals.  It is also applicable for non-drip and thick impregnated insulated cables.

Two main types of heat-shrinkable tubing are used: cross-linked polyethylene type and silicone rubber type, which can shrink evenly when exposed to heat. When heated to a specific temperature, the heat shrinkage tube will shrink, while the hot melted adhesive will naturally cool to form a good seal layer.

2. What Should You Pay Attention To When Dealing With An Electric Bending Machine Cable Protection Tube?

Answer:

1. The bender should understand its performance and familiar with the operating knowledge of the personnel to operate
2. Proper checking before use to ensure that buttons, operating handle, travel switch should be intact, and the bender must also be reliably grounded
3. The choice of molds should meet the requirements of the required bending radius
4. There should be sufficient scope of activities around the construction site
5. Hands and feet are strictly prohibited from coming in contact with its rotating
6. The work should be completed in time to stop the power and release the oil pressure

3. What Is The Content Of The Cable Inventory And The Meaning Of The Cable Number?

Answer: A wire and cable inventory form the foundation for placing a cable order. It also guides the construction, operation, and maintenance of the cable’s archival data. Cable inventory should contain data on cable number, starting point, type, specification, length, and cable classification statistics. The control cable should also be listed in each spare cable core.

The wire and cable number acts as a critical cable identifier. Thus, it is essential not to repeat a particular cable number throughout the plant. Ideally, a specific cable number has a particular meaning and regularity that can express the characteristics of the cable.
