Transmission Line...

Transmission Line Arresters TRIDELTA, Chống sét van trên đường dây cao áp TRIDELTA

Transmission Line Arresters

Effective Protection of overhead lines from lightning overvoltage to improve line availability and stability of the electrical grid. Design as NGLA-Types (Non Gapped Line Arresters) with silicone housing

Transmission Line Arresters

For more and more cases surge arresters are applied as transmission line arresters besides the typical application as station arresters.

Line arresters are an effective and economical option to protect existing as well as new transmission lines against lightning overvoltages in order to increase grid reliability and availability of transmission lines. Line arresters are suitable especially for line sections with low earthing impedance of the line towers, areas with high lightning activity, transmission lines without shield wire protection and for transmission lines with very high demand to their availability.

TRIDELTA offers NGLA-type line arresters (Non Gapped Line Arrester) based on our arrester series SBK and SBKC with silicone housing, completed by a variety of corresponding connecting and assembling variants e.g. wire clamps ensuring an easy installation to different tower-, insulator- and line configurations.

We are pleased to offer you a solution, which fits to your situation, please contact us!

Monitoring

In addition to the range of surge arresters, Tridelta Meidensha also provides different monitoring devices.

"smartCOUNT" is an intelligent surge arrester monitoring system. It measures leakage current as well as impulse currents automatically and can delivers online accessible measuring values and trend curves. Please visit our smartCOUNT page to see more Information.
http://www.smartcount.info/

Our “DCC series” counters, with or without leakage current measurement, and our spark control gaps can also help to detect early malfunctioning before it leads to a threatening of the security of supply.
