Plastic spool for process turnover spool

The plastic spool is made of specialized engineering plastic through injection molding, featuring high precision and advanced structure. The side plates are reinforced with ribs, providing good balance performance, high strength, and resistance to acid and alkali corrosion, with a balance accuracy of up to grade 6.3 or higher. The overall structure is plastic, combined with metal components to ensure the requirements for shaft holes and electrical conductivity. The product's parts can be replaced, making maintenance convenient. The plastic spool is mainly used for the winding and unwinding processes in the production of optical fiber cables; for the winding and unwinding processes in the production of data communication cables, including series connection, twisting, and cabling; and is suitable for high-speed winding of RF cables and wire and cable, as well as for winding and unwinding in high-twisting machines and extruders.

Technical measures for the safe connection of high-voltage cables.

Technical Measures for Safe Connection of High Voltage Cables 1. The wiring work of high voltage cables must be carried out by dedicated electrical operators and specialized electrical maintenance personnel. Operators must undergo training in "Safety Operating Procedures" and relevant specialized technical training, and must pass examinations to obtain an operating qualification certificate before they can operate electrical equipment. 2. Operators must strictly implement the power-off and power-on system before stopping or supplying power. Before operating the main circuit of high voltage electrical equipment, operators must wear insulated gloves of the corresponding voltage level, wear high voltage insulated boots, or stand on an insulated platform; strictly implement the "Two Ticket System". When stopping the switch cabinet, the circuit breaker must be turned off first, followed by pulling the isolating switch.
