Electrical protective sleeve

The tail vertebra of the protective sleeve can be tailored according to the wire diameter. This flexible design allows the protective sleeve to better fit wires and cables of different diameters, ensuring optimal performance

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.
