Open design for easy installation
When the connector is overloaded or overheated, the sheath will produce a noticeable color change: the yellow, green and red sheaths are consistent with the colors of the three-phase wires. When a phase wire is overloaded or overheated, the sheath color can immediately undergo an "irreversible color change" to alert the on-duty electrician that the "phase voltage" change may have serious consequences.
Multi-diameter adaptability
Suzhou Qingyan Technology Co., Ltd. produces protective sleeves for wire and cable connectors. Each size of the sleeve is compatible with more than two wire diameters, which can meet the needs of various usage scenarios.
Flexible cutting design
The cone-shaped tail of the protective sleeve can be cut to fit different wire diameters, and this flexible design allows the protective sleeve to better fit wires and cables of different diameters, ensuring the best performance.
