Application context
METAENERGY cast-resin busway — up to 10 kV, IP68, for substations and harsh environments. Used where cable systems cannot meet operational or dimensional requirements. Customers include substation owners, energy service and electrical contractors, oil and gas, chemical, metallurgical, and transport infrastructure facilities.
Typical challenges
- Cable replacement is limited by constraints on dimensions, supports, and routing.
- Specifications require moisture, dust, and aggressive environment protection with documented certification.
- Fire safety requirements can only be met with complete certification package and current datasheet.
- Proper interface with MVA/MVS low-voltage distribution is required.
METAENERGY solution

- Housing resistant to chemicals, UV, and high-pressure washing. Characteristics certified per datasheet.
- Fire operability of at least 240 min — per datasheet. Datasheet and catalog provided for acceptance.
- Direct interface with MVA and MVS busbar trunking per project specifications and catalog.
When to choose cast-resin busway
When cable systems cannot provide the required IP68 protection, chemical resistance, or fire performance, design organizations consider cast-resin busway. This applies to compact enclosed substations, high-density equipment retrofits, and installations with limited mounting space.
Cast-resin busway is used in generation and distribution circuits up to 10 kV, with rated currents up to 6300 A. System service life is specified in the type datasheet; certain configurations claim a service life comparable to long-term operation of cable lines under similar conditions.
Below — STA and STS cast-resin busway series (up to 10 kV, IP68). Cast-resin busbar trunking IP68 up to 1 kV is a separate SVA/SVS series; link in the range section below.

METAENERGY cast-resin busways are available in two conductor materials — aluminum and copper. Both series have IP68 protection, are installed from factory-ready sections, and are compatible with MVA/MVS busbar trunking.
Each product line includes sections with rated currents from 800 to 6300 A in 1L, 2L, 3L configurations. Specific section types and part numbers are available in the manufacturer's catalog.

Comparison with Cable Systems
Key operational differences between cast-resin busway and traditional cable installations. Data is provided per catalog and product datasheet.
| Parameter | Cable System | METAENERGY IP68 Busway |
|---|---|---|
| Protection rating | Depends on configuration, typically below IP68 | IP68 (complete protection against dust and water) |
| Fire resistance | Determined by cable type and penetrations | Fire resistance of at least 240 min, per datasheet |
| Chemical and UV resistance | Requires additional enclosures | Proven resistance, housing withstands chemicals and UV radiation |
| Installation | Significant time for routing and termination | Factory-assembled sections, installation per design (time and cost savings per quote) |
| Service life | Depends on operating conditions — per cable line datasheet | Per busway type datasheet; specific value in technical documentation and product certificate |
| Connection to MVA/MVS | Transition assemblies required | Connection per catalog and design solutions |

Advantages
Cast-resin busways address requirements where not only electrical parameters matter, but also environmental resistance and ease of installation.
Integration into low-voltage distribution
Connection to MVA and MVS busbar trunking systems per design solutions, without extra adapters when geometry is coordinated. Conductors and connection assemblies are agreed upon at the design stage.
Verified specifications
Heat dissipation through housing, fire resistance, mechanical strength — parameters are documented in the product datasheet. Scope of acceptance testing is determined by the project and specifications.
Performance in harsh conditions
Housing is non-combustible, rodent-resistant, does not create draft. Suitable for a wide range of climatic zones, including Arctic and desert environments — per version datasheet.
