Insulators ISHOS-10-20 are based on insulating parts and made of tempered glass. This design feature makes it
easy to identify the damaged insulator. In case of breakdown of the insulator, insulating piece of tempered glass
breaks into many small fragments. Thus ISHOS cannot be formed as a result of crack during electrical or mechanical
abuse, through which will be a short circuit to ground, and it is impossible to detect such an insulator without electrical
testing. In the event of breakdown or micro cracks insulation item located in the state of stress as a result of hardening
breaks and points to the failed insulator. The pattern of destruction is identical to suspension insulators made of
tempered glass.
Advantages of special insulators ISHOS-10-20 for disconnectors PLHD against porcelain insulators ONSH-10-20:
TYPE TESTS
- Excludes the fall of the insulator and knife PLHD to the operator from a height of support;
- high value-more than withstood the breaking load (more than 2 times)
-more than the high value of resistance to dynamic shocks (more than 20 times)
- Earthquake resistant, vandal-proof
- No hidden defects in the insulating body.
Assemblage
The mechanical strength of the insulator ISHOS through design features is limited only by the strength of the metal
pin of the bottom ﬂange.
External inspection ( outer view and marking )
Useful service life- 30 years.
Weight, length of insulating part,
ﬁtting dimensions, armature spacing
correspondence
Quality and thickness of armature’s
anticorrosional coating
Testing load at bending ( torsion ) 1 min. withstand.
Deviation angle control at bending ( torsion ) and
absence of plastic deformation at bending ( torsion )
Alternating short term test voltage
in dry condition
Failing load at bending (torsion )
Evaluation of partial discharge level
Hydrophobic resistance to water
Hydrophobic resistance to coloring liquid
Adhesion of coating layer to insulating body
