Project-Specific Selection
Based on load, operating mode, and environment — rating, design, and insulation are determined strictly per catalog and technical passport.
Main IP55/IP66 and cast-resin IP68 busbar trunking up to 1 kV
For industrial and civil facilities
Key features
Components and Documentation
Joint units, tap-off units, specifications, assembly drawings, technical passport — supplied per catalog.
Insulation Reliability
Halogen-free and phenolic resin-free insulation, operating temperature up to 150 °C, service life of at least 25 years.
Fire Protection for Penetrations
Kit with mineral fiber boards and adhesive provides fire resistance up to 240 min — per documentation.
Application Scope
Low-voltage busbar trunking up to 1 kV is designed for main distribution of electrical power in industrial and civil facilities. Used from transformer substation infeeds to high-power loads and consumer switchboards.
Common Challenges
- Joint connections: improper installation (torque or alignment failures) leads to localized overheating and insulation damage.
- Incorrect selection of current rating and dimensions — underspecification or overspending on the project.
- Design not matching environmental conditions (IP per IEC 60529) — accelerated degradation and risk of failure.
- Incomplete project documentation and specifications — re-approvals, schedule delays.
METAENERGY Solution
- Supply of busbar trunking with load-based selection, documentation, and components per catalog and technical passport.
- Joint units and tap-off units — per catalog, housing with cooling fins.
- Continuous overload up to 120 % — confirmed by technical passport and type test reports.
- Application in projects with GOST and IEC requirements, local Russian manufacturing.
Typical Installation Sites
Industrial plants, warehouses and logistics centers, shopping and business centers, residential complexes, administrative buildings. Especially in demand where main distribution, tight installation schedules, and convenient connection of units from main switchboards and transformer substations are required.
Cast-resin busway IP68 — SVA and SVS series; main distribution IP55/IP66 — MVA and MVS. Conductor material, degree of protection, and design type are selected per catalog and technical passport.

Sizes and selection
Specific ratings, section lengths, corner and tap-off configurations are selected from the catalog and data sheet. Approximate series structure is shown below.
Busbar trunking series and conductor material
| Series | Conductor material | Protection rating | Type |
|---|---|---|---|
| MVA | Aluminum | IP55 / IP66 | Main line |
| MVS | Copper | IP55 / IP66 | Main line |
| SVA | Aluminum | IP68 | Cast resin |
| SVS | Copper | IP68 | Cast resin |
Busbar trunking vs. cable system comparison
Using busbar trunking instead of cable trays provides time and cost savings. Key parameters — according to METAENERGY materials.
| Parameter | METAENERGY busbar trunking | Cable tray |
|---|---|---|
| Installation speed | Twice as fast due to prefabricated sections and mounting hardware | Longer installation time with termination and routing of each line |
| Cost savings | Up to 30% of total cost compared to equivalent cable scheme | Higher costs for installation, cable management systems, and connections |
| Overload capacity | Insulation withstands up to 150 °C, continuous overload up to 120 % | Cable insulation is typically rated for 95–105 °C |
| Heat dissipation | Convection and heat radiation through housing with cooling fins | Insulation layers trap heat |
| Load connection | No separate termination required for each tap-off point | Termination and separate connection required |
Insulation service life — at least 25 years
