We TEST.
模拟真实条件对测试电缆至关重要,可确保其在各种情况下的可靠性和性能。以下是电缆模拟测试的示例,特别侧重于电缆
测试目标:评估电缆在真实条件下的电气性能和耐用性。
- 环境室:将电缆放置在可控制温度和湿度的环境室中。模拟电缆在其使用寿命期间可能遇到的极端条件,例如高温、低温和湿度变化。
- 振动测试:使电缆经受振动以模拟它们在运输过程中或在动态环境中可能遇到的条件。使用具有不同频率和振幅的振动测试设备。
- 弯曲和屈曲测试:严格弯曲和屈曲电缆以模拟安装和使用条件。使用自动弯曲装置对电缆施加受控应力,并评估其柔韧性和抗弯曲疲劳性。
- 拉伸强度测试:通过对电缆施加受控拉力来评估电缆的拉伸强度。测量导致故障所需的力,确保电缆能够承受安装过程中或负载下可能遇到的张力。
- 磨损测试:通过将电缆在粗糙表面上摩擦来模拟磨损条件。评估电缆的耐磨性,确保它们能够承受实际安装中常见的磨损。
- 电气性能测试:在正常和极端条件下进行电气测试,包括高温和低温。测量电阻、电容和绝缘电阻等参数,以确保电缆在各种环境中保持其电气性能。
- 化学暴露测试:将电缆暴露在工业或住宅环境中可能遇到的常见化学品中。评估电缆的耐化学性,确保它们在不同环境中都能正常工作且安全可靠。
- 电缆的电气性能应保持在规定的公差范围内。
- 暴露于环境压力后,不应出现明显的损坏或性能下降。
- 电缆应能承受弯曲、屈曲和拉力而不会发生故障。
- 抗震和抗磨损性能应达到或超过行业标准。
- 化学暴露不应导致电缆完整性严重恶化或受损。
Endurance Test
Cable's life-cycle is simulated using drag-chains with different running lengths at different speed and accelleration.
| Run | Accelleration | Speed |
|---|---|---|
| 2 m | 6 G | 600 m/min |
| 5 m | 4 G | 400 m/min |
| 15 m | 2 G | 200 m/min |
| 110 m | 0.5 G | 100 m/min |
Single / Bunch Torsion Test
The cable, or bundle of cables, is rotated according to the imposed angle tothe right and to the left while undergoing a downward pulling force (F). Each alternating motion is considered a cycle.
| Diameter Ranges | Rotation Angle | Test Length |
|---|---|---|
| 5 - 50 mm | ± 540° | 1000 mm |
| 5 - 50 mm | ± 360° | 300 mm |
Alternate Bending Test
The cable specimen to be tested is moved at different speeds and accellerations (sometimes abruptly) to simulate tension, torsion and bending. Part of the cable is attached to a weight, the rest is guided over two pulleys. Each run is considered a cycle.
| Running Lenght | Accelleration | Speed |
|---|---|---|
| 5 m | 4 G | 400 m/min |
Tick / Tock Test
The type of test requires the cable to be subkected to a bending regime (each of which is considered a cycle) based on different load parameters.
The maxium tensile load is 3000N. The maximum cable diameter is 50 mm. The test is comparable to the analogue DIN VDE 0281 Part 2.
| Diameter Ranges | Rotation Angle | Test Length |
|---|---|---|
| 5 - 50 mm | ± 540° | 1000 mm |
