"Tension stringing equipment" refers to a specialized set of machinery and tools used to install overhead conductors and cables (like ACSR, AAAC, OPGW, etc.) while maintaining them under a controlled, pre-set tension. This method prevents the conductor from dragging on the ground or fouling on obstacles during installation.

It is crucial for modern overhead transmission line construction because it:

• Protects Conductors: Eliminates scrapes, nicks, and damage to the conductor surface, which can compromise its electrical and mechanical integrity.

• Ensures Safety: Minimizes risks to personnel and property by maintaining adequate clearance over roads, railways, existing power lines, and other infrastructure.

• Achieves Precise Sag: Allows for accurate control of conductor tension and sag, which is critical for line performance, preventing excessive stress, and ensuring clearance standards are met.

• Enhances Efficiency: Facilitates faster installation, especially over long spans or difficult terrain, compared to traditional slack methods.
