Cable laying methods

1. In Which Case Is Row Pipe Laying Used? What Are The Advantages?

Answer: The laying of rows of pipes is generally used in places where they intersect. This is often done in buildings, roads, or railways, and sometimes also in dense structures. The main advantage of row pipe laying is that it occupies less space and can withstand large loads. Also, the wires and cables do not affect each other. Thus, it is safer.

2. What Is The Long-Term Permissible Load Capacity Of A Cable?

Answer: The long-term permissible load capacity of a wire and cable is its specified current after thermal stabilization. After current stabilization, the cable conductor reaches the long-term allowable working temperature.

3. What Are The Factors That Determine The Long-Term Allowable Load Capacity Of A Cable?

Answer: Three main factors determine the long-term allowable load capacity of a cable. The factors include;

1. The long-term permissible operating temperature of the wire and cable
2. The thermal performance of the wire itself
3. Cable installation and the surrounding environment of the heat dissipation conditions
