Industry has many instances of current carrying cables that are critical to the success of theapplication. Power is nearly always mission critical; reputation, client confidence and mostimportantly lives can all be at risk if current carrying cables fail. Cables are routinelyterminated using a metal tag that is crimped to the copper conductor. Because there are manyvariables in both the material and crimping processes, the quality of the connection and hencereliability is also variable. Industry has several strategies to combat these variables: Strictcontrol of materials and processes, visual inspection and destructive testing.Material and process control is expensive and time consuming and offers no guarantee thatcabling and wiring will not degrade over time. Visual inspection is time consuming, onlychecks the physical appearance of the connection and in a manufacturing environment canonly be used to sample batches.Destructive crimp testing, usually using a pull test or cross section micrograph can only inferthat delivered crimp quality is good. It too is heavily reliant on the sampling methods usedand wastes materials as irrespective of whether the crimp (cable) passes or fails the test, itmust be discarded. If one crimp fails the test, then the whole production batch must bediscarded.Because there is no fast, low cost test available that can be used on 100% of all cables, veryfew suppliers can actually test the crimped cables they deliver. For this reason, manyelectrical/engineering industries record crimp failure as a serious challenge to reliability.Engineering solutions Ltd have pioneered an innovative Direct Crimp Resistance System,which enables all production crimps to be tested non-destructively in seconds using Kelvin techniques without any stress to the crimp or cable. This means all mission critical cables can be tested as electrically fit for purpose prior to shipment saving time, money, wasted resourcesand possibly lives.

工业上有许多载流电缆的实例，这对应用的成功至关重要。电力几乎总是至关重要的；如果电流传输电缆发生故障，声誉、客户信心以及最重要的生命都可能受到威胁。电缆的端接通常使用金属标签，该标签压接在铜导体上。由于在材料和压接过程中存在许多变量，因此连接的质量和可靠性也是可变的。行业有几个策略来对抗这些变量：严格控制材料和工艺，目视检查和破坏性测试。材料和工艺控制既昂贵又耗时，而且不能保证电缆和布线不会随着时间的推移而退化。目视检查是耗时的，只能检查连接的物理外观，并且在制造环境中只能用于取样批次。破坏性卷曲测试，通常使用拉力测试或横截面显微照片，只能推断交付的卷曲质量良好。它也严重依赖于所使用的采样方法和浪费材料，无论压接（电缆）是否通过测试，都必须丢弃。如果有一个卷不通过测试，那么整个生产批次必须被丢弃。因为没有一种快速、低成本的测试方法可以100%地用于所有电缆，所以很少有供应商能够真正测试他们提供的卷曲电缆。因此，许多电气/工程行业将卷曲故障记录为对可靠性的严重挑战。工程解决方案有限公司开创了一种创新的直接抗压系统，该系统可以使用开尔文技术在几秒钟内对所有生产卷曲进行非破坏性测试，而不会对卷曲或电缆造成任何压力。这意味着所有关键任务电缆都可以在发货前进行电气测试，从而节省时间、金钱、资源浪费和可能的生命。
