GB/T 1001.1 Insulators for overhead lines with nominal voltages above 1 000 V Part 1: Porcelain or glass insulator elements for AC systems Definitions, test methods and criteria
| Maximum test force | 500 kN (two sets, each set with a load of 500 kN, each set can work independently) |
| Complete machine accuracy level | Class 1 |
| Control mode | Closed-loop control (force-deformation-displacement closed-loop control) |
| Test force measurement range (kN) | 1%~100%F·S (5kN~500kN) |
| Stretch piston stroke | 0~300mm (including preload stroke, convenient for installation and removal of specimens) |
| Test force resolution | ±500000 yards |
| Test force indication accuracy | ±1% |
| Deformation measurement range (mm) | 1%~100%F·S |
| Deformation resolution | ±500000 yards |
| Deformation indication accuracy | ±1% |
| Displacement measurement range (mm) | 300 |
| Displacement resolution (mm) | 0.01 |
| Displacement indication accuracy | ±1% |
| Test speed range (mm/min) | 0.5~120mm/min (loading control speed can be set arbitrarily in this range) |
| Speed accuracy | ±1% |
| Connection mode | 56*4 internal threads at both ends (can be changed according to user requirements) |
| Tooling connection hardware | Two sets of marks 16, 20, 24, 28, 32 each |
| Safety protection | Electronic limit protection |
| Overload protection | Automatic alarm and shutdown when the maximum load exceeds 3% |
| Overload protection | This machine is a real-time three-closed-loop control automatic adjustment. When the actual test force is higher or lower than the set test force due to abnormal conditions, it has an automatic adjustment function. |
| Load holding function | The test force is 96 hours (or longer) of load holding, and the load holding time can be set arbitrarily |
| Nominal internal volume of environmental chamber | 3.6m3 |
| Nominal internal dimensions of environmental chamber | W4500×D800×H1000mm |
