Production Line
Raw materials adopt special wood pulp with deep purification treatment to remove substances that weaken dielectric stability. Purified pulp is delivered to wet-laid equipment to continuously form paper web with uniform and controllable thickness and density. Calibration process adjusts paper density to fit working conditions of medium-voltage capacitors. Real-time online monitoring system tracks physical parameters of paper sheet during production. Thermal setting procedure fixes the arrangement of fibre structure. All jumbo rolls pass lab tests including voltage resistance and strength before storage. Independent trace codes are assigned for each batch to realize full-link information tracking from raw materials to finished goods.
Each roll of medium‑voltage electrolytic capacitor paper is wrapped with moisture‑proof film and kraft paper to avoid dampness and surface abrasion. Paper rolls are securely fixed on export pallets, then loaded by truck for inland transportation.
Pre-shipment inspection is carried out to check roll appearance and surface condition.
Lead time: 7‑14 working days after deposit confirmation.
Standard export pallet packing is available, custom packing is acceptable.
We work with reliable freight forwarders to guarantee safe global shipment.
