Description:

15kV surge arrester

HIVOLT surge arresters have below outstanding characteristics
1. Long Duration Current Impulse:
Depending upon the system impedance and system conditions, power lines can discharge currents of low magnitude for significantly long durations as compared to a lightning stroke. MOV block samples are subjected to 18 to 20 discharges each with a current magnitude and duration  with one minute cooling interval between each discharge.
The sample discharge voltages are verified before and after long duration discharges with a 10 kA 8/20 μs current wave to confirm no damage.
 
2. Accelerated Aging:
Ensuring stable arrester performance, after installation, is a necessity. MOV blocks are
thermally aged at 115°C for 1000 hours at voltages specified by standards while continuous measurements of disc watts loss are recorded. Excellent stability is demonstrated with a continuous reduction in watts loss for the entire test period.
 
3. Heat Dissipation Behavior:
The intent of this test is to ensure that the prorated test sample used for durability design tests has a thermal cooling characteristic that is slower than or equal to the actual unit. All prorated samples showed a slower cooling rate than a complete unit, demonstrating sample validity.

4. Operating Duty Performance:
Distribution systems are affected more by lightning strokes than switching
operations. The probability of the number of strokes and the magnitude of these strokes depend upon several factors that cannot be controlled or predicted accurately. our arresters are tested to ensure they are capable of withstanding high current impulses while demonstrating thermal recovery.
During this test, the MOV test samples are subjected to twenty 8/20 μs lightning strokes and two 4/10 μs high current impulses of specified magnitude followed by another 8/20 μs discharge voltage verification impulse. The prorated sections demonstrated thermal
stability.

the surge arrester shed material is silicone rubber . color is grey .

we can also offer NEMA brackets A type or B type , it depends on customer's requirements.

 

Applications:

Used for distribution lines or substations , the major funtion is to protect line from lightening impulse .

​guarantee live line runs safety . Generally for 15KV distribution lines.

 

Competitive Advantage:

All HIVOLT surge arresters are made of high class raw material : bloocks , fiber glass tube , silicone rubber sheds , brackets etc.

we will offer most competitive price to assist customers save their budget .

OEM product available .
