Line Lightning Protection Devices (LLPDs) SAd21z are installed in Switzerland
12.12.2016At the beginning of December Streamer experts Alexander Nefedov and Igor Zavyalov supervised the installation of more than 60 pieces of SAd21z on 16 kV line belonging to the utility called BKW, servicing the canton of Bern. The overhead line has a number of specific features: it comprises wooden and metal poles, and quite an extensive section of it passes along the agricultural fields, far from trees and other items that could shield poles from direct lightning strikes. Within a year, Streamer R&D designers developed the way in which SAd21z could be fixed on the customer’s poles by using an additional cross-arm and light composite insulators provided by LAPP (Germany), one of the oldest European partners of the Company. Now almost all the metal poles and the poles on the open section of the line are protected by Streamer’s LLPDs.
Despite of the fact that Switzerland is not a country of high lightning activity, local power engineers try to ensure faultless operation of distribution power lines on the highest level. The LLPDs were installed in extremely short terms to make sure that time of power interruption was not more than 2-3 hours. In the course of SAd21z installation employees of BKW noted, how simple it was to assemble and mount the devices on the line.
Swiss power supply systems share positive experience in the use of innovations. In case of successful application of the technology, other companies will also be ready to implement it. That gives Streamer a chance to expect some new projects in this country in the coming months.
Why protecting the line against lightning with a CLG? or LLPD?
CIGRE 2022 finished last week
Streamer met with its old friends over the world - it was a nice and warm event, the first big one after the Covid times. CIGRE was also very useful in setting up new cooperation opportunities, mostly in the European region.
First LLPD installation for E-Distribuzione near Oderzo, Veneto, Italy
In 2019, the University of Napoli contacted Streamer Electric AG in order the find a lightning protection solution for medium voltage lines. Prof. Amedeo Andreotti was looking for medium voltage line protection devices for E-Distribuzione, the Distribution utility of Italy, part of the ENEL group owner of the electrical network in Italy but also many other electrical networks around the world. E- Distribuzione is actively looking to improve the lightning outage rate on their overhead line network and particularly in the northern part of Italy.

First installation of TRANSEC units in Ecuador
Vietnam Ha Giang Power Company will test Streamer innovative devices of lightning protection.
Ha Giang is a mountainous province with a complex topography and experiences extremely high lightning density during the thunderstorm season. 110 kV lines in the province mostly pass through mountainous terrain, many rivers, and streams, so breaks of the line wires due to lightning, are not uncommon. Most of the problem areas are concentrated in areas such as the Nam Ngan hydroelectric power plant and the city of Viet Kuang. Installation of innovative lightning protection devices to provide the region with uninterrupted power supply was necessary.
