Application FAQ

Yes. Avantar provides several products applicable to solar and renewable-energy installations.

The current portfolio includes solar panel mounting fasteners, grounding and earthing products, flexible laminated copper busbars and composite electrical components that can support different parts of a renewable-energy system.

Solar panel mounting fasteners include self-drilling screws, T-bolts and complete fastening sets (M6-M12), available in hot-dip galvanized carbon steel or SS304 / SS316 stainless steel. They are designed for installation scenarios including metal roofs, fiber-cement roofs, ground-mounted solar systems, building-integrated photovoltaic applications and solar carports.

Grounding products such as copper-clad steel ground rods, solid copper ground rods, hot-dip galvanized ground rods, ground helical screw anchors and grounding clamps can be used as part of grounding systems for solar installations.

Flexible laminated copper busbars are suitable for high-current connection applications such as battery packs and energy-storage systems, where flexibility helps accommodate vibration and thermal expansion.
For solar and energy-storage projects, product selection should consider installation type, electrical requirements, outdoor exposure, grounding requirements, dimensions and mechanical conditions. 

Avantar provides several grounding and earthing products for electrical installations, power systems, substations, industrial equipment and renewable-energy applications.

The current range includes:

• Earthing busbar insulator supports - Epoxy resin or SMC insulator with galvanized steel bracket. Heights: 40 mm / 60 mm / 80 mm. Rated voltage up to 36 kV. Insulation resistance ≥1000 MΩ. Mounting: M8 / M10 / M12 bolts.

Different grounding electrodes and connection components address different installation and material requirements. The appropriate grounding solution should be selected according to the grounding design, installation method, soil and environmental conditions, conductor configuration and applicable project requirements.  

Avantar provides cable accessories covering cable termination, cable joining, cable fixation and cable-entry protection.

The current cable-accessory range includes:

• Cold-Shrink Silicone Cable Termination - Designed for medium-voltage XLPE cable termination applications, with configurations covering 10 kV, 20 kV and 35 kV systems. Made of high-quality silicone rubber with integrated stress control. No heating equipment required during installation. Each kit contains main tube, stress cone, sealing parts and installation accessories. Suitable for indoor and outdoor use. Compliant with IEC 60502 and IEEE 404.
• Waterproof Armoured Cable Intermediate Joint - Straight-type cable-splicing kit for connecting two sections of armoured power cables. Provides electrical continuity, waterproof and dustproof sealing, plus mechanical shielding. Supports low-voltage and medium-voltage armoured cables. Available with plastic or metal shell. Suitable for underground, underwater and outdoor installations.
• Trefoil Cable Cleats - For three single-core cables in trefoil formation. Cable diameter 20 mm-100 mm, short-circuit withstand up to 85 kA peak. IEC 61914 compliant.
• Single Cable Cleats - For individual cable fixation. Cable diameter 10 mm-90 mm, operating temperature -40 °C to +120 °C. LSFH PA66 material. IEC 61914 compliant.
• Armoured Cable Cleats - For XLPE and SWA armoured cables. Cable diameter 20 mm-120 mm, short-circuit withstand up to 100 kA peak. Aluminum alloy or SS316 material. IEC 61914 compliant.
• Cable Glands - For cable-entry sealing and strain relief. Materials: nickel-plated brass, SS304, nylon PA66. Threads: Metric M12-M63, PG7-PG48, NPT. Cable diameter 3 mm-50 mm. IP66 / IP68 protection. Armoured and unarmoured versions available. Compliant with IEC 62444 and EN 50262.

Cable glands should be selected according to cable construction, cable diameter and required protection level. 

Preformed armor rods and deadend grips are overhead-line fittings designed to provide conductor protection, mechanical support and tension management.

The products are designed for ACSR, AAC and AAAC conductors and cover conductor cross-sections from 16 mm² to 600 mm² according to the product information. Material options: galvanized steel or aluminum-clad steel wire.

Their helically preformed structure allows installation without special tools and helps distribute mechanical stress around the conductor.

Preformed armor rods protect conductor surfaces from abrasion and vibration-related damage at suspension points, reducing metal-fatigue risk caused by long-time wind vibration.

Deadend grips are used for tension and anchoring applications at overhead-line terminal sections and dead-end points.

For correct selection, the conductor type, conductor cross-sectional area, conductor diameter, application purpose and required product length should be confirmed.

Matching the fitting to the actual conductor specification is important because an incorrect size may affect grip performance and conductor protection. Compliant with IEC 61284 and ISO 9001.
