Optical cable connection box is mainly used in protecting the splices of optical fibers between two sections of optical cable, reserving a section of optical fiber in the connection box for maintenance.
The connection box has excellent sealing property, wateproof and dampproof. It could not be corroded on the power line.
Connection box has two types, middle connection box and terminal connection box. Middle connection box is used in butt Joint between two sections of optical cable in the middle of line: the terminal connection box is used in line terminal, Optical cable line terminal coupling or connection protection between optical fiber or jumper of optical cable.
Electric power optical cable connection box has pole type or tower type according to operating environment.
It has metal type and non-metal type (plastic) according to difference casing material.
1) Plastic connection box is used in splicing and branch protection of ADSS and ADSS optical cable.
2) Compare with the plastic connection box, metal connection box has obvious advantages, such as mechanical strenghth sealing property and corrosion resistance. It could repeating open, dilatation, maintenance and incremental connection etc. It is used in OPCW optical cable generally.
