Network Case

The frame owns reliable earthing system.

Alarms parts include unit, bar, and row alarming and general alarm (sound and light).

Contacting parts are gilded, silver plated, tinned, nickelplated and taken embalmment.

All plastics are fire retardant engineering plastic.

Overvoltage protector applies high quality gas or semiconductor tube, overcurrent protector applies high quality macromolecule PTC or ceramic PTC. These two protector operates exactly and reliably and acts rapidly. Besides it has good nonstick performance.

It has satisfying defence performance that damages to communication equipment and personnel in machine room by overvoltage and overcurrent which are caused by thunders and other reasons can be prevented.

The general distribution frame consists of inline security connector bar, rank testing connector bar, security unit and other accessories.

It is in full-module structure, and it is agile and easy to deploy and assemble

Single-faced frame combines advantages of double-faces frame while saves space, all operation is carried out on obverse and is free from long jumper.

Double-faced frame is manufactured by special aluminum sections, it is easy to assemble and is designed in two styles of structures to get it dilatable.
