ZMBK series single-phase dry type Isolation transformer

ZMBK sries single - phase dry type isolation transformer adopts high quality material and advanced technology , it has advantages of damp - proof and convenient maintenance, it can be applied to such power transmission and distribution places like underground railway , high building, airport, station, wharf, enterprise, tunnel, etc. It is mainly used in power supply occasions of AC 50~60Hz and voltage less than 500V. All the input and output voltage , connection group and capacity of tapped winding can be designed and produced according to users’ requirements.

1.Quality control

transformer quality control for very customer very important.we control quality from very one spare part.especally silicon sheet. see picture below we buy silicon sheet testing.if you want to know more information how about our how to keep stabilizer quality good.pls contact our email.

2. Quality Guarantee

we give our customer isolation transformer quality guarantee period 2 years if proper loading we give customer 5 years and adopt our technician suggestion.every isolation transformer we first testing part quality then assmbel finished testing output and loading testing.after testing finished we make dynamic testing.after packing we testing again.see below our testing equipment

3.If isolation transformer get any problem or have any specially design inquiry.we will reply customer within 24 hours.bcos our sale person is technician.

like three phase isolation transformer big current loading for output and DC voltage output and surge protect and over-loading protect.full power loading design.silicon area and winding wire size design specally.

see below picture with isolation transformer control

4.OEM/ODM available

we accpet customer OEM or ODM.customer send to our your logo and company name and packing box design.if no have design.we can design for customer.then printing voltage stabilizer panel logo and company name.samll power carbon box we printing customer logo and company too

5.we accpect sample order testing our quality.

at make sample before we confirm all specification no problem.first we will testing by our sale person.after we testing finished.we will send to customer check quality.small power sample we give customer sample for free.customer pay shipping cost.
