Travel crates IL-1 are intended for installation of transformers, relays, small resistors, cutting the signal cable, connect the devices to the rails of track circuits using jumpers.

floor devices are steel casing with caps welded construction and safety pipes for cable protection. The grooves are laid rubber gaskets covers that protect against ingress of moisture and dust devices.

Additionally, the device can be equipped with jumpers. Sizes jumpers and their number is determined by the specific project and stipulated in the contract.

Electrical insulation of current-carrying parts of the housing relative to the cabinet checked 1500 V AC at 50 Hz.

The insulation resistance of live parts with respect to the cabinet body in normal climatic conditions, not less than 200 megohms.
