The Outdoor Telecom Cabinet is widely used in wireless communication base station, such as 3G system, communication/network integrated service, access/transmission switching station, emergency communication/transmission, etc.
The cabinet, made of hot dip galvanized steel, is a double wall cabinet with 20mm PEF insulation between inner plate and outer plate. The cabinet includes equipment compartments and battery compartments . It is easy for installation and with perfect sealing performance.
Equipment Compartment: The upper part of the cabinet is equipment compartment, which is separated with the battery compartment by division plate, for heat insulation of the equipment compartment.
Battery Compartment: The lower part of the cabinet is battery compartment, which is used for installing batteries.There’s heat insulation cotton between the cabinet inner wall and outer wall for keeping temperature. The cabinet includes air exhaust device for release of harmful air generated by the batteries.
Door and Door Lock: The cabinet door uses embedded structure. The door opening angle is larger than 110° and the door limit device can limit the opening angle. The lock is theftproof three point lock, supports padlock. There’s open door alarm sensor, which works together with the environment monitoring unit.
Cabinet Size : 1300mm×760mm×2150mm (W×D×H)
