Above Ground Closure
Issue: Legacy above ground closures are susceptible to moisture ingress by virtue of their location of deployment, i.e. mounted on overhead poles or on the eaves of buildings. When cables are damaged between the distribution point and customer premises it is cost prohibitive to change out the entire cable.
Solution: Dexgreen has developed a highly versatile above ground closure that can be used to repair damaged networks and house multiple connectors to repair customer connections. It is more resilient to water and moisture ingress than legacy closures, by virtue of its unique design. The key features of this solution include:
- Application: Can be used for joints at end user fixings and carrier poles, i.e. the eaves of houses. Best suited for joining damaged cables, where gel-filled crimp connectors are used to form connections.
- Capacity: Slots are on the ends of the closure to facilitate the introduction of a small cable tie to hold the dropwires during installation which make construction easier. A deep base in the closure makes it easier to dress the connectors. A maximum of 11 CWI8As can be fitted in the closure (8 for jointing pairs and 3 for the strength members.
- Cable compatibility: Only 1 dropwire joint, at the customer fixing position is advised, unless exceptional circumstances apply. All drop wire joints on poles must use the above ground closure attached to the drop wire clamp. It can be used on poles carrying a long dropwire route to provide dropwire joints and should be secured horizontally to the dropwire clamp.
- Installation: The closure must be secured by cleating the cable to the building / structure at either end of the closure. It should not be secured to the dropwire clamp at the end user premises. It is recommended that this is not can carried out at a height greater than 2m above ground when end user fixing position is not accessible.
