Description
Perforated rolling trays are part of the metal cable support systems of the IEK group of companies. Designed for laying and protection of power and low-voltage cables. When used in conjunction with a cover, it provides maximum cable protection against external influences, dust and moisture. Depending on the version, the trays can be used both inside public, industrial buildings, structures and retail facilities, as well as outdoors under a canopy, in the open air, as well as in rooms with high humidity. Rolled perforated trays IEK are made of rolled cold-rolled steel, galvanized by a conveyor method in accordance with GOST 14918-80 or by immersing finished products in a zinc melt GOST 9.307. The IEK rolling tray system consists of straight elements and accessories designed to change the direction of the route, as well as covers and connecting elements of various sizes. The perforated tray is produced according to TU 27.33.13-002-83135016-2017. In terms of safety requirements, the product complies with the technical regulations TR TS 004/2011 and GOST R 52868-2021.
Advantages
- Power losses lowered by 30% as compared to PN-2 fuses due to the updated modern construction, manufacturing technology and quality of applied materials.
- High resistivity of receptacle (insulator) base to mechanical stress owing to the use of reinforced thermosetting plastic.
- Lowered by 10-20% overall dimensions as compared to PN-2 fuses.
- Wide range of PPNI fuse links including fusible elements with rated current from 2 to 630 A. 82 units in total in 6 sizes.
- Overload protection due to the current-limiting function providing for lowering prospective current short circuit current by several times.
- Wide range of operating temperatures: from -45 to +60 °C. It allows applying PPNI in various climate zones.
- High breaking capacity: at 660 V – 50 kA, at 500 V – 120 kA.
