Order Information

STBThe distribution box is mainly used as a distribution device between the main line of the telephone cable network and the user branch line, with specifications of5-50pairs. The shapes of the distribution box include: aluminum alloy shell indoor and outdoor distribution boxes, embedded wall distribution boxes, pole-mounted distribution tubes, etc.,嵌壁式分线箱、抱杆式分线筒等。

Technical specifications:

lThe distribution box uses a terminal rotating clamp airtight wiring method for incoming lines, ensuring that the core wire connection points are not exposed and are reliably connected;

lThe outgoing lines of the distribution box use screw compression, eliminating the need for manual stripping of the insulation layer. Operation and maintenance are convenient and reliable;

lThe contact points of the distribution box are sealed with silicone grease, anti-corrosive, waterproof, and moisture-proof, ensuring safety and reliability.

lThe shell of the distribution box is made of aluminum alloy or cold-rolled plate, shaped and surface sprayed, with sealing rings for the incoming and outgoing cable holes, providing good sealing performance. The outdoor cable distribution box is used in the following environment: 有密封环，密封性能好。室外电缆分线盒使用环境:

lEnvironmental temperature:-55℃～+55℃；

lRelative humidity: <95%；

lAtmospheric pressure:70～106KPa.

lEnvironmental temperature:-25℃～+40℃；

lInsulation resistance: under standard atmospheric conditions≥5x104MΩ；

lContact resistance: under standard atmospheric conditions≤5mΩ；

lDielectric strength: AC500Vone minute without breakdown or arc phenomenon
STBModule with over-voltage protection

Product Introduction

A device designed to prevent personal and equipment damage from over-voltage. It consists of a base and a plug-in component, used for connecting and disconnecting cables and providing over-voltage protection.
