1.1. Construction features
CLARKIA transformers have been designed and manufactured strictly in accordance with standards IEC 60076-6.
Coils:
Coiling is made of copper class H-Grade 2/thermal class H.200, according to IEC 60317-3.
Insulation varnish for this copper is a polyester-IMIDA modified THEIC with a polyamide-IMIDA overcoat. This kind of winding wires are homologated according to UL-E103536 (NEMA MW-35C).
All our coils lack insulation boards, which makes them very reliable for humidity in tropical and marine climates, etc…
Insulation is achieved through fiberglass separators class F.
Coils have been designed and manufactured for use in a room temperature of 45ºC with insulations class F (155ºC) and a class B temperature increase (70ºC), always considering the continuous operation.
Optionally, copper strips can be also used.
All coils can carry additional regulation intakes +2,5%, -2,5%, +5%, -5%,etc… upon customer request.
Core:
We work with the best qualities of magnetic mat, supplied by the world’s leading manufacturers (ThyssenKrupp, f.e.).
Dimensional tolerances of materials fall within standard DIN 41.302 (Part 1).
Also magnetic properties of materials fall within standards EN 10106 and EN 10107.
All magnetic mats comply with REACH and RoHS regulations.
Varnishing:
Each unit is carefully varnished with anti-flash alquidic varnish.
Once mature, the product complies with the following international standards: BS 5629: TYPE 1.1 (CEI 85) with class F insulation.
A fungicide comes standard, which provides total protection class 0 (no growing) according to standard BS 3900 PTG 6, an additional characteristic suitable for tropicalization and using in warm, humid climates.
Metal casing:
Casing is manufactured with steel plates, 1,5. mm thick. Firstly, it is subjected to degreasing and pickling and subsequently a 70-90 microns layer of epoxy polyester powder coating is applied in furnace.
Protection of the box is IP23 (other protections available upon request)
Paint color is RAL 7035 (other colors available upon request)
– Our manufacturing is backed by a quality assurance system based on the ISO 9001 standard. – All units are tested unitarily and shipped with their corresponding test certificate in accordance with IEC 60076. |
