2. Description

The DDTE027 Outdoor Telecom Enclosure includes two cabinets, which works together. The two cabinets totally include three compartments. The three compartments can be battery compartment, equipment compartment, cable distribution compartment or MDF compartment. The structure can be custom made. The cooling options includes air conditioner, heat exchanger and fan. It is mainly 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 galvanized steel, is divided into equipment compartment, battery compartment, cable distribution compartment. The equipment compartment is separated from the battery compartment for heat insulation of the equipment space. The battery compartment is used for installing batteries. The cabinet body has heat insulation foam, which can keep the temperature inside the cabinet. The cabinet also has roofs which is sun proof and water proof. There’re ventilations for releasing harmful gas generated by the batteries.

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. There’s open door alarm sensor, which works together with the environment monitoring unit.

2.1 Wire Routing Design

Feeder cable and other external cables all use bottom wiring method.

2.2 Grounding Protection

• The cabinet includes grounding copper bar with anti-corrosion coating. There are enough screws for wiring connection terminals.
• The metal part of the cabinet should be interconnected and be connected with grounding bar. Connection resistance between any two points is lower than 0.1Ω.
• Protective earthing of other equipments inside the cabinet should be connected to the grounding bar.

2.3 Door lock theft proof design

(1) Damage resistance of the theft proof lock meets GA/T 73-1994 “Mechanical Anti-theft Lock” class B requirement, supporting padlock.

(2) Three point lock

2.4 Connection and Fastening

• Use anti-loose threaded connection as structure and bearer connection. Anchor bolt for fixing cabinet use hot dip galvanized bolts.
• Door hinges use inner hinge mode.
