What’s New For Hygienic Mechanical Seals
loaded silicon-carbide material that will reduce seal face wear, increase uptime, and offer twice the service length of competitive components. The PGS-100 material enhances seal face pressure-velocity characteristics beyond that of monolithic sintered silicon
Safety, Health & Environment
The silicon carbide arrester has some unusual electrical characteristics. It has a very high resistance to low voltage, but a very low resistance to high-voltage. When lightning strikes or a transient voltage occurs on the system, there is a sudden rise in voltage and current.
Thin aluminium oxide passivation layers for solar cells | …
One way to increase the efficiency is by diminishing the losses that are present in the energy conversion processes inside the solar cell. Passivation layers are able to prevent unwanted premature recoination of electrons and electron holes within the silicon, allowing these charged particles to leave the solar cell and do their ''power generating'' job.

An arrester with lead length of 10 feet can typically add 60 kV to the arrester discharge voltage during fast-front lightning surges. Typical arresters used in this type (13.2 kV system, 95 kV BIL) of installation would discharge such a surge at about 36.5 kV, making the total voltage surge on the trans- …
