MJPT/MJPTN pre-insulated sleeves offer UV-resistant, waterproof branch jointing for LV-ABC overhead lines with clear markings and full EN 50483-4 compliance.
WANGYUAN MJPT / MJPTN Series Pre-insulated Sleeves are designed for LV-ABC overhead systems with neutral messenger conductors. Made of UV resistant polymer insulation, they are pre-filled with jointing compound and fitted with elastomeric sealing rings for superior waterproof performance. Clear moulded marks indicate crimping sequence, cable size and stripping length, with color-coded rings for quick specification identification. All products comply with EN 50483-4 and NFC 33-021 standards, and pass the 6kV 1-minute underwater water tightness test for reliable outdoor service.
– Cross-section of conductor can be easily identified by the color code of rings
– Elastomeric ring and pre-filled grease enable super waterproof performance
– Water fightness test carried out at ókV for 1 minute under water

Elastomeric sealing rings and pre-filled jointing grease deliver excellent water tightness, verified by 6kV 1-minute underwater test. It effectively blocks moisture intrusion and maintains stable insulation performance in humid outdoor environments.
The insulation tube is made of weather and UV resistant polymer, with outstanding aging resistance and environmental adaptability, suitable for long-term operation on outdoor overhead distribution lines.
Moulded marks on the body show crimping sequence, cable size and stripping length; color-coded end rings allow quick and accurate cross-section recognition, reducing construction errors and improving on-site installation efficiency.
High strength plastic ensures stable conductivity and uniform crimping deformation with reliable tensile strength. Standard dimensions match dedicated crimping tools for simple and efficient on-site operation.
