Technical Features:
The main body of the prefabricated joint is pre-assembled internally within the company, making it ready for use by simply inserting the cable end during on-site installation.
Capable of connecting cables with different conductor cross-sections to form transition joints.
Fully dry structure without any insulating liquid or gas, eliminating the risk of leakage.
Utilizes special resin materials and modern casting processes with stringent quality control through individual X-ray inspections.
Compact design, small volume, lightweight, and minimal installation space required. Suitable for cable trenches, manholes, direct burial, and similar applications.
Optionally available with waterproof and explosion-proof casings based on installation environment requirements.
