PEL distribution transformers range includes oil immersed core type transformers, Dry type (VP impregnated) transformers and autotransformers. These transformers are tailor made for various ratings. IEC or national standards are followed. We offer distribution transformers voltage up to 33 kV and ratings up to 30 MVA. PEL offers transformer tanks with corrugated walls, detachable radiators and tubular arrangement.
PEL transformers are available:
Distribution Transformers (Pole /Pad Mounted)
Chokes for furnace Transformers
Any other special requirement
Extensive experience and success in manufacturing distribution transformers led to the establishment of power transformer division in 2005. Since its birth the division has produced transformers of ratings 31/40MVA, 20/26MVA, and 10/13MVA for ratings up to 132 KV. In order to provide its customers the best of technology and products of international competence, PEL has combined its technical expertise with GANZ, a renowned and experienced Hungarian transformer manufacturer.
PEL is also exporting Power Transformer to International customers for their special requirements and specifications. PEL power transformers are equipped with best transformer accessories like OLTC from MR (Germany), High Voltage Bushing from PASSONI & VILLA (Italy), Buchholz Relay from EMB (Germany), insulation material from WEIDMANN (Switzerland), silicon steel from THYSSEN (Germany), and cooling fans from SCHORMANN (Germany). Material of the windings is usually 99.99% pure electrolytic copper. Multiple conductors as well as CTC are used in winding. The magnetic cores are manufactured from cold rolled grain oriented (CRGO) steel sheets. A robust clamping structure, jointing technique, cutting and mitering of laminations ensure low no load losses. The steel sheets in the core limbs and in the yokes are clamped together by glass-epoxy bands.
Dry type transformer
There are primarily two main manufacturing techniques for dry type transformers; Cast Resin and Vacuum Pressure Impregnated (VPI) with their own typical features. The main difference is their insulation class; Cast Resin is Class F (155°C) and VPI is Class H (180°C). The Vacuum Pressure Impregnated transformers not only offers in-build safety feature but there are many other advantages of using these transformers such as improved reliability, reduced losses, minimal maintenance, enhanced overloading capability etc.
PEL’s Initiative for Technology Transfer
considering these advantages of dry type transformers, Pak Elektron Limited (PEL) took the initiative and went into a Technology Transfer Agreement in March 2007 with DuPont Pakistan Limited (DPOL) for Designing and Manufacturing of Vacuum Pressure Impregnated dry transformers with Nomex® paper. PEL is now pleased to announce that PEL will be the first local company in the production of dry type transformers in Pakistan.
Advantages of Dry Type Transformers with VPI Technology using NOMEX®
Enhanced Safety With the increasing costs of low voltage cables, it has become a trend to bring high voltage lines close to installed loads. For cost reasons, transformers are located near habitable areas such as buildings where fire risk has to be minimized. Additionally, industries such as chemical, mining, etc. are also a potential risk of fire. Ventilated Dry type transformers (VDT) have no fluids to spill, explode or burn, and the insulation used (NOMEX®) does not support combustion in air.
Dry type transformers can be located close to their loads, such as; inside factories, schools, hospitals and apartments and as a result low-voltage lines can be shortened with a consequent reduction of the related losses.
Increased Reserve Capacity
If transformers are to be operated continuously at or near their rated loads, efficiency is of prime importance. In this case, one could select 80°C-rise in VDT units insulated with NOMEX®, allowing these units to operate continuously above (potentially up to 30 percent more than) the rated load.
Transformers are inherently reliable pieces of equipment. Surveys published by IEEE show failure rates of modern ventilated dry-type transformers equivalent to conventional fluid-filled units in the same power and voltage classes.
Dry type transformers require an annual inspection and only cleaning of dust which can block path of the cooling medium i.e. air. This is only where the maintenance is required to be carried out. This considerably reduces the running cost.
Reduced Cost of Cabling
VPI transformers installation does not require particular fire safety arrangements; consequently the transformers can be installed near the load. This results in reducing the high costs of LT cabling.
Resistance to Humidity
Vacuum pressure resin impregnation of the insulation paper covering the conductors and the other insulation components make it resistant to moisture and polluted atmospheres.
Friendly to the environment
In these transformers, no liquids is used, thus no risks for any kind of leakage, moreover, no toxic or corrosive gasses, nor halogens are released from the transformer in case of any accident/fire. At the end of their useful life, VDT units can easily be dismantled, and the copper (or aluminum) conductors recovered, along with the steel core.
Improved Capability for Harmonic Loading
Transformers supplying loads with heavy harmonic content frequently see high hot-spot temperatures. Standard transformers typically reduce the base temperature to compensate, which increases the size of the unit.
Following are some key products in LV category.
LV Distribution Panel
Indoor and outdoor type sheet steel fabricated, free standing, front or rear accessibility, cable or bus duct connections are supplied complete with air circuit breakers, molded case circuit breakers, load break switches, necessary meters, relays and instruments etc. Breakers of either fixed or draw–out versions can be supplied as required.
