Fiber FOG CLS Dome

Fiber FOG CLS Dome
Fiber FOG CLS Dome
Product Code : FOG1236
Product Description

We are a known manufacturer and exporter of FOG-CLS-Dome001, which is widely used for Direct burial, Cable duct,  Aerial and for Well. This is known for providing airtight and watertight environment. The fiber splice closure of this delivers a hermetic seal and as per the needs the closure can be used for burial and aerial applications. In addition to this, the closures of FOG-CLS-Dome001 are are compliant with IEC 1073-1, these are made of tough and anti-corrosive polycarbonate.  Polycarbonate makes the closures ideal for duct, aerial, cable direct burial and well applications.

Methods and Conditions


 Air Tightness  

 No air bubble seen  

 Put closure under water for 15min with closure's  internal air pressure set at 100kPa±5kPa.

Remains 100kPa±5kPa

Measure the internal pressure 24 hours later

 Air Tightness after    re-installation  

  No air bubble seen and pressure remains  unchanged

Do re-entry and re-installation 3 times and repeat above Air Tightness Tests.

 Resistance between  

Soak closure into water in 1.5m-depth for 24hrs,
and measure the insulation resistance after taking it out of water.

 metal parts: 2.0x105m

Resistance between  

 each metal part and  

 ground: 2.0x105m
