PULL-A SERIES
Overhead Conductor / OPGW Creep Testing Machine
UNIVER PULL-A Series Overhead Conductor / OPGW Creep testing machine is designed to perform creep test on overhead conductors and OPGW cables in accordance to IEC 61395.
The purpose of test is to verify the long-term creep of overhead conductor or OPGW when holding a fixed tension. Creep results in further sagging after installation.
Features:
- The machine is designed with electromechancal loading system which enables constant and smooth loading to apply tensile force to the specified test load, typically 20% RTS.
- Multiple test stations are available to have several tests be running simultaneously
- 0.5μm resoluton extensometers offer stepless adjustable extensometer gauge lengthes to meet different applications
- Every station with independent control system and data logging software ensures the highest reliability for long time running, particulary for creep test lasts 1000 hours (42 days)
- UNIVER Patented alloy socket method for terminal preparation on overhead conductors is a recycleable and efficient way, one terminal preparation typically takes less than 30 minutes which has much higher efficiency than conventional expoxy resin method which normally takes at least a whole day to cure, besides, the expoxy resin is one-time usage and costly.
