Comewill, a professional voltage transformer manufacturer in China, proudly presents the JDZX9-35D/290 Voltage Transformer, engineered for stable and accurate performance in 35kV power systems.

As a professional manufacturer of power equipment in China, Comewill introduces the JSZV18-24R Voltage Transformer. Featuring a fully enclosed, epoxy-resin-cast insulation structure and equipped with elbow-type plugs, this transformer offers superior resistance to contamination and moisture. It is specifically designed for indoor medium-voltage systems with ungrounded neutral points and is suitable for applications involving voltage monitoring, energy metering, and relay protection.

As a professional manufacturer of power equipment in China, Comewill introduces the JDZ16-24R Voltage Transformer—a fully enclosed, epoxy-resin cast indoor device. It is suitable for medium-voltage distribution systems rated at 24kV and below, and is compatible with both 50Hz and 60Hz frequencies. Featuring a built-in fuse, this product effectively addresses voltage anomalies and provides reliable overvoltage protection.

The JDZ(X)11-20/225 Voltage Transformer from Comewill factory adopts an epoxy resin cast fully enclosed structure, specially adapted for power systems with rated frequencies of 50Hz or 60Hz and rated voltages of 15kV and 20kV.

Welcome (Wenzhou) Electric Co., Ltd., a professional switchgear Dehumidifier manufacturer in China, our high quality smart Instrument Room Dehumidifier 30W runs on semiconductor cooling tech. A built-in fan pulls damp air from sealed cabinets into the dehumidifying duct. As air passes through the cooling unit, moisture turns to liquid water. This water drains right out of the cabinet through a dedicated tube — dehumidification works fast and reliably.

Comewill factory's Mechanism Room Dehumidifier 15W is your go-to solution for sealed electrical cabinets. Bulk orders, sample requests, competitive pricing — we've got you covered for all sourcing needs. Powered by semiconductor refrigeration, this unit uses an internal fan to pull humid air from the sealed cabinet into its dehumidification duct. As air passes through the cooling module, moisture condenses into water, which then drains out of the cabinet through a dedicated pipe. The dehumidification effect is consistent and reliable.
