Stringing Equipment
Definition
Stringing equipment encompasses the full system used in overhead line construction to pull wire from a reel and set it at the correct tension. Key components include: a bull wheel tensioner controlling tension as wire is paid off the reel; a puller drawing the wire through stringing travelers (temporary sheaves) mounted on each structure; a pulling rope or pilot line preceding the conductor; and the force measurement instrument — typically a dynamometer — installed inline to monitor the tension applied during both the pulling and sagging phases. For T&D distribution stringing, 5-inch AP models in the 10,000–20,000 lb range are standard. For transmission and EHV stringing, higher-capacity 10-inch AP or EDxtreme configurations are used.

Why Stringing Equipment Matters
How Dynamic Measurement Uses It
DMS's AP dynamometers — specifically the 30006-0084 (28% of total Dillon sales), 30006-0100 (19%), and 30006-0050 (10%) — are the instruments most commonly used in active stringing equipment setups across the utility industry. DMS's technical staff understands the inline installation configurations used by major T&D contractors and can recommend the correct model for specific conductor types, tension targets, and span configurations. For projects requiring digital data output with remote monitoring, DMS can configure EDxtreme plus Communicator II systems.
