PSV160A Glass Disc Suspension Insulator 170 mm Height

PSV160A glass insulator is a designation for a toughened glass suspension insulator in the “fog profile / cap & pin, ball-and-socket coupling” family. It is sometimes equated with U160BSP / U160BLP under IEC naming or the GOST-class equivalent “PSV160A”. It’s used in high-voltage overhead transmission lines, in suspension string configurations (i.e., multiple units in series to reach the desired voltage rating).

Typical use cases & advantages

Use Cases of PSV160A Glass Disc Suspension Insulator：

For HV transmission lines where you need both electrical insulation and mechanical support of conductors / ground wires.
Especially in polluted or harsh outdoor environments where glass’s favorable self-cleaning, resistance to aging, and stability make it attractive.
Suitable for use in string insulator chains: depending on line voltage, multiple units are used together to meet required voltage rating and to provide safety margins under pollution, wet conditions, etc.

Advantages of Glass Suspension Insulators：

Stability & long-term aging resistance — glass doesn’t degrade as much over decades compared to some polymers under UV or chemical exposure.
Good mechanical strength for its mass, and the design (fog profile, multiple sheds) helps with creepage distance and leakage control under pollution.
Clear failure mode — if cracked, it often gives visual indication (crack or break), aiding maintenance.
Ease of manufacture in precise shapes — glass can be molded with tight tolerances and is less variable in dielectric behavior.

What to Check When Sourcing PSV160A Glass Insulator?

When you (or your procurement team) source PSV160A, ensure the following:
  • Standards & testing certificates — type test reports per IEC 60383-1 (for mechanical & electrical), verification of leakage, power-frequency, impulse tests.
  • Dimensional matching — cap and pin coupling dimensions must match (ball diameter, socket geometry, locking device).
  • Surface profile / fog vs standard — fog profile yields increased creepage and is good in high pollution zones.
  • Coating / sleeve / galvanizing — some units may use zinc sleeves or RTV coatings to protect against corrosion of metal parts.
  • Residual mechanical strength — ensure the residual (post-break) strength meets specs (often ~80% of full load).
  • Quality of glass, internal annealing / tempering — defects like inclusions or internal stresses reducing dielectric strength must be controlled.
  • Packaging & shock protection — proper separators, cushioning, handling for international shipping.
  • Warranty, replacement, spare units — important for long-term system support.
