Due to electromagnetic induction, the metal shielding layer (or metal sheath) of long line high-voltage single core power cables generates induced voltage, which leads to aging of insulation and reduction of insulation grade, resulting in reduced cable life. Once the induced voltage exceeds the sheath breakdown voltage, the outer sheath is broken down, forming a multi-point grounding fault of single core cables.

Three phase combined zinc oxide arrester with composite sheath is a new type of protective appliance used to protect the insulation of power equipment from over-voltage hazards. It effectively limits the over-voltage between phases while limiting the over-voltage between phases and ground. It is widely used to protect vacuum switches, rotating motors, parallel compensation capacitors, power plants, substations, etc. This kind of combined arrester has been used for more than ten years, and the practice has proved that it is a practical and effective measure to limit the interphase overvoltage.

Features of arrester with series gap □ Product model description1. Under normal conditions, the series gap of the arrester isolates the arrester from the system, and the arrester does not participate in the operation, thus prolonging its service life;2. For the system with frequent voltage fluctuation, the gap can be broken down to make the arrester work only when the voltage exceeds the specified value, avoiding the frequent action of the gapless arrester;3.

Numerous of these manufacturing processes are based on laser technologies such as laser melting, sintering or build-up welding. Other processes, such as binder jetting, are completed by a sintering pass to fully cure the material. In order to localise and detail thermal conspicuities in these processes, InfraTec infrared cameras support the determination and subsequent adherence to thermal process parameters by in-line monitoring. Infrared cameras can be integrated directly into the process control system to enable a non-contact and non-invasive temperature measurement.

Another critical factor to consider in dealing with Russian clients is their business practices and ethics. Russia has a unique business culture that is heavily influenced by its political and economic climate. The country has a complex legal system that may differ from that of other countries, and as such, it is essential to hire a local attorney when drafting a contract or a business agreement.In conclusion, hosting a visit from Russian clients can be a challenging but rewarding experience.
