Underground Cable Branch Joint Connectors Introduction
At Xi'an OUKAMU, we take pride in our pioneering advancements in cable connection technology. Our Underground Cable Branch Joint Connectors represent a significant leap forward in cable branch connection products, offering unparalleled ease, safety, and reliability. Developed in 2015, our integrated T-connector (integrated brancher) is designed to facilitate the connection of multi-core main and branch cables with minimal disruption, making it an ideal solution for modern infrastructure projects.
Composition of underground cable branch joints
Includes a branch terminal body, insulating housing, sealing tape, and resin adhesive.
Sealing Tape
Function
Wrapped around the outer sheaths of the main cable and branch cables, it seals the clearances between the cables and the respective feedthrough opening (for the main cable) and branch outlet in the protective enclosure, thereby preventing the ingress of dust and solid particulates into the housing.
Performance & Characteristics
Single-sided adhesive coating (pressure‑sensitive) Elastic material providing flexibility to accommodate minor deformations
Easy and convenient on‑site application Excellent sealing performance, ensuring reliable protection
Flame‑retardant, complying with relevant safety standards for cable accessories
● Dielectric Withstand Voltage Performance
•For IP65‑rated integrated T‑connector terminals: After damp heat conditioning at 91 % to 95 % relative humidity, an applied voltage of 3.5 kV for 5 minutes shall not cause phase‑to‑phase breakdown.
•For IP68‑rated integrated T‑connector terminals: After immersion in water at a depth of 1 m for 1 hour, an applied voltage of 3.5 kV for 5 minutes shall not cause phase‑to‑phase breakdown.
•Standards Compliance: The products meet all applicable requirements of Q/OKM01‑2018 "Integrated T‑connector terminals (integrated branch devices) with rated voltage 0.6/1 kV".
•Certified Testing: The products have been successfully tested and certified by the National Quality Supervision and Testing Center for Wire and Cable and by Oukamu Electric Co., Ltd., with all tests passed.
