Polymer housing
Durable polymer with fiberglass, resistant to chipping and impact loads. Complete set of test reports.
IT 10 kV traction insulators
Polymer insulators for force transmission between parts of electrical apparatus at different potentials
Key features
Application in apparatus up to 10 kV
Disconnectors, load break switches, coil assemblies, drive mechanisms. Operation in conditions from –45 to +40 °C.
Exact compliance with the project
Order strictly by designation from the catalog or design documentation. Substitution of type without verification is excluded.
Comprehensive supplies
Possibility of supplying IT together with MN, IO, IP insulators and SHMGI busbars — one supplier.
Application area and typical tasks
IT traction insulators are in demand by manufacturers of power circuit apparatus, as well as repair and service organizations. They transmit mechanical force between parts at different potentials and are used in disconnectors, load break switches, electromagnetic mechanisms.
Typical market approach
- Quick selection of a "similar" type without detailed verification
- Risk of supplying an insulator that does not match the design documentation
METAENERGY approach
- Supply strictly according to exact designation and passport
- First verification of type, designation and documents — minimizing errors
Critical points when purchasing
An error in the insulator type leads to non-compliance with design documentation and rejection during acceptance.
When a specific model is discontinued, replacement is only possible through coordination with the equipment developer.
Maintenance organizations often lack a complete set of drawings — this increases the risk of ordering the wrong version.
Mixing insulators from different manufacturers without cross-checking designations is unacceptable.
METAENERGY supplies IT insulators as a catalog item with end-to-end compliance control against specification data. This helps avoid errors and reduces selection time.
Products
The IT traction insulator line for 10 kV voltage includes two base series with different support section lengths. Each version has modifications determined by the threaded stud size or copper busbar — selection is made via catalog.
All insulators are made of polymer with fiberglass reinforcement and have a built-in steel stud with protective coating.
IT 160/10
IT 160/10 traction insulator
Basic design with support section length of 160 mm. For transmitting force between parts of equipment at different potentials.
- Rated voltage 10 kV, maximum operating 12 kV — per data sheet
- Test voltage 50 Hz (1 min) 42 kV — per type data sheet
- Polymer body with fiberglass, stud with zinc coating
- Modifications by stud size and thread pitch — per catalog
Order by designation IT 160/10-xx from catalog. Replacement of another manufacturer's type — only after verification with equipment design documentation.
IT 240/10
Traction Insulator IT 240/10
Design with extended support part length of 240 mm for equipment with increased dimensional requirements.
- Rated voltage 10 kV — according to passport
- Application in disconnectors and load-break switches up to 10 kV
- TU 3494-002-97798631-2011
- Test protocols — according to batch documentation
Designation: IT yyy/10-xx, where yyy is the support part length (160 or 240), xx is the modification according to catalog.
Standard sizes and selection
Selection is based on the exact designation from the catalog or equipment design documentation.
Basic types IT 10 kV (according to type certificate)
| Type | Rated voltage, kV | Test voltage (50 Hz, 1 min), kV |

| Stud | Zinc-coated steel | Built-in embedded fixture |
| Voltage class | 10 kV | Application — according to passport and project |
| Documentation | Passport, test reports | Per batch |
Supply by exact designation
IT insulators are ordered by catalog designation or equipment specification. Type verification is mandatory when replacing discontinued items.
Advantages
METAENERGY catalog item with product documentation and the option for comprehensive supply of related components.
Impact resistance
Polymer housing is not subject to chipping and breakage during transportation, unlike ceramic analogs — by product material.
Dielectric strength
Polymer provides insulation between equipment parts at different potentials — parameters per datasheet.
Related nomenclature
Ability to close an IT request together with MN, IO, IP insulators and SHMGI busbars from a single supplier.
Additionally for the designer
Precise designation
Order only by catalog code or drawing — without selecting a "similar" type.
Replacement of discontinued types
In case of shortage of design — coordination with the device developer and verification of designation.
Temperature range
Operation in conditions from –45 to +40 °C — according to the type certificate.
Do not mix manufacturers
Types from different manufacturers are not considered interchangeable without step-by-step verification of design documentation.
