Product Description

SG(B)10 type-this series Dry-type Distributing Transformer has strong withstanding of thermal shock, overload capability. Besides, it has many good points such as flame-retardant, low-loss, and low partial discharge capacity, low noise, no harmful gas and no pollution. 
 
Core
The iron core applies imported high-performance cold-rolled magnetic conductive silicon-steel
plate;it applies 45°fully-inclined joint form. 
Between the layers of winding, it applies flexible
fastening device and makes no-load loss and noise low.
 
 
HV, LV coil materials
The high-voltage and low-voltage coils are made up of Nomex insulating material and dipped in solvent-free immersion paint many times by VPI vacuum pressure device and is solidified by high temperature baking.After dipped, the coil has a good performance moisture proof, impacting resistance and no chapping, no partial discharge. It can be decomposed and recycled.
 
Shield Cover
IP20 and IP23, depending on the requirement of the users
 
Over-thermal Protection
 
 Over-load Ability
Adopts new structure, material and new craftwork; 
It has good points of good heat dispersion, long thermal endurance and extensive strong overload capability. 
It can work under 120% overload or work over a long time safely and reliably. 
Under the situation of IP23, it can run overload over a long time without fan to cool. 
 
Safety
SG(B)10 type-this new kind of product is now the dry-type transformer of highest security performance. 
All the insulating material is flame-retardant, self-extinquishing and non-poisonous. Its combustible material only takes less than 10% of the epoxy resin product. 
No poisonous gas is produced.
 
Reliability
With special coil design, craftwork and material,
Good feature of 3-proofing protection function: moisture proofing, mold proofing and salt mist proofing. Good thermal impact resistance, no chap and no partial discharge.
The insulating system based on Nomex can always keep the best state of electricity performance and mechanical characteristic during the entire period of usage of transformer. 
 
Excellent Dampproof
Nomex insulating system dry-type transformer,
Can sufficiently prevent the invasion of moistrue.
It applies the advanced VPI equipment and vacuum dipping technology.
With high-quality impregnating varnish appmved by UL, 
it can keep running over a long period under 180°C or higher ternperature.
Nomex   paper is entirely peretrant dipped by immersion paint.
 
Smaller volume, less weight
Nomex paper of Du Pont for main insulating material,
takes it as the mixed insulating system in the hottest place of transformer
more compacted and less weight when compared with the epoxy resin cast transformer of the same capacity.
 
Environmental protection
SG(B)10 type product can be decomposed and recycled. Epoxy resin cast transformer that is made up of dry resin and glass fiber which overcame the disadvantages of traditional can not be decomposed after its useful period and pollutes the environment.
 
Lead-out wire
The outgoing terminal of the high voltage coil in fixed is the top of the winding, and its tapping head is connected with the middle of the winding.

 
 
 
Working Condition
Its working conditions is basically as stated in "GB 6450-1986 Dry Power Transformer", item 1.2. Altitude lower than 1000m, surrounding temp lower than 40°C; 
Prouduct standard
GBl09411-2007, Dry power transformer
