This outdoor AC disconnector from DNK (Xiamen) Electrical is rated at 200 amps and designed for high voltage power systems operating between 10 kV and 40.5 kV at 50 Hz or 60 Hz. The unit uses silicone rubber insulators that provide waterproofing, lightweight construction, and resistance to brittleness in harsh weather. All conductive contact parts carry a silver coating of at least 20 micrometres to prevent oxidation and maintain low contact resistance over the service life.
The disconnector employs a surface contact method rather than point contact, which distributes current more evenly and reduces localised heating. A stainless steel disc spring bowl keeps the two contact parts tightly engaged, contributing to very low resistance across the joint. The lever-operated pull ring with a shift lock pin provides a reliable manual breaking mechanism, and the mechanical life is rated at 2,000 operating cycles. The base plate is available in stainless steel or hot-galvanised finish for corrosion resistance in outdoor installations.
DNK (Xiamen) Electrical supplies this switch to buyers in the electric power, railway, mining, and oil field sectors across multiple markets. The product complies with IEC 62271-102, ISO 9001, and several Chinese national standards including GB 1985-2004 and GB/T 11022-1999. Payment options include T/T, Western Union, and PayPal. Shipping is available by sea, air, or express, though specific lead times and minimum order quantities are not stated on the listing and should be confirmed directly with the supplier.

When sourcing a 200 amp high voltage disconnector from DNK (Xiamen) Electrical, first verify that the rated voltage, current, and short-circuit withstand values match your system's design parameters. Request the full IEC 62271-102 type-test report and check that the tested ratings cover your specific installation conditions, including altitude correction if your site is above 1,000 metres.
Confirm the exact packaging method and shipping dimensions before booking freight, as outdoor disconnectors with porcelain or composite insulators require careful handling to avoid mechanical damage in transit. Sea freight from Xiamen port is standard for heavy electrical equipment; ask whether the supplier uses wooden crate packing with internal bracing and moisture barriers. Clarify incoterms (FOB, CIF, or DDP) and ensure the commercial invoice matches your import licence requirements.
Upon receipt, inspect the silver coating on contact surfaces for uniformity and check that the silicone rubber insulator shows no cracks or surface defects. Operate the disconnector through several open-close cycles to verify smooth mechanical action and proper lock-pin engagement. If the unit will be installed in a high-pollution area, confirm the creepage distance is sufficient for your pollution level classification and consider requesting an extended creepage variant from the supplier.
