The ZP-ES1 device is designed to prevent birds from being electrocuted on overhead power lines (OPL) through fecal streams. Additionally, its use reduces the risk of OPL outages caused by electrical flashovers of insulators due to contamination by bird droppings, corrosion products, and other pollutants flowing from the crossarm onto the insulators. The device complies with the requirements of STO 34.01-2.2-011-2015 of PJSC "Rosseti" and is manufactured according to TU 3449-001-52819896-2013.

Depending on the sizes of the "caps" of various insulators, the device has the following modifications:

• ZP-ES1M: for insulators type PS70, PSD70, PSV70
• ZP-ES1S: for insulators type PS120, PSV120
• ZP-ES1B: for insulators type PS160, PS210, PS240

The device is approved by the Russian Bird Conservation Union.

Design Advantages

• Made of plastic resistant to ultraviolet radiation, bird droppings, mechanical loads (wind, ice-wind, etc.), and electric arc.
• Non-flammable material (flammability class FV(PV)-0 according to GOST 28779).
