A Russian glass suspension fog style, special profile made in several colours, aqua, blue and greenish. Only made in this one size. . From the manfacture's website I found this description.

Minimum Strength: 70 kN Weight: 4,6 kg . glass linear suspension insulator PDS-70s (for areas with high degree of pollution of the atmosphere) is used for electrical insulation and fixing the wires and ground wire overhead transmission lines and switchyard substation high voltage 6-500 kV. . At high power lines high voltage applied garlands, composed of sequentially connected by a hinge means insulators PDS-70s. Number of insulators PDS-70s in the garland is determined by voltage class lines, construction of supports, the type of insulator, the operating conditions. . On wooden poles at a voltage of 35 kV put two suspended prison PDS-70s in garland; on metal poles - one or two more prison. . Number of suspension insulators PDS-70s for VL 6-35 kV is chosen regardless of the height above sea level. . To avoid inadvertent decoupling garlands rod in a groove of fixed caps lock. . The letter "E" in the marking insulator PDS-70s denotes the index modification insulator and indirectly characterizes the period of issuance. . Thus insulators PDS-70, PDS-70A, PDS-70B, 70B-PDS, PDS-70g PDS-70D are now obsolete and are not allowed.

ПСД-70Е: Standards shipment insulators PDS-70s: : 100 pcs container 3t: 200, container 5t: 500 pieces
