• The joint closure for OPPC is quite different from OPGW and ADSS because it is electriferous during the run-time, it will affect directly to the line safety and normal operation once it is going wrong. According to voltage class, OPPC joint closure needs to adopt the appropriate insulator.
• The joint closure of OPPC is divided into joint-box and Terminal Box. Joint closure is installed among towers and poles, plays the role of fibre splicing, protection and power transmission. Terminal Box realized the final optical-power separation.

OPPC Connector box is divided into Column type and Suspended type connector box. Column type connector box requires special platform for the fixation during the usage. Column type connector box is fixed onto tower with help of link fittings.

Note:
If customer needs other high-voltage OPPC joint closure, please contact with our company.

OPPC joint closure is electriferous during running, so it cannot be installed directly onto the pole and tower same as the OPGW and ADSS joint closure. Generally, the existing electric power line is not designed with platform for displaying the joint closure. A safety and reliable Joint closure platform should be designed separately in according to dimension of pole and tower. Meanwhile, this platform can serve as a temporary foot platform for construction and maintenance.
