Overview
The automatic cable reelers are supplied with an explosion proof polycarbonate junction box (K241EX) or Stainless Steel junction box (K247EX). A cable reeler is normally placed on the roof of a floating roof tank structure where it ensures electrical continuity between linear heat detection (LHD) sensor cable and the fire detection system during the upward and downward movement of the floating roof. The cable reeler ensures that the cable remains taught and prevents that cable from getting jammed in the moving parts of the roof.
Installation
Installed on the top rim of a tank body, the cable is connected to a junction box (eg. 1-B6782-190) on the tank roof. The reeler follows the movement of the roof, uncoiling the cable as the roof lowers, and winding the cable when the roof rises.
Application
The 1-53836-K241EX supports a cable drop of up to 25m. For hazardous areas, suitable safety barriers are required.
