Substation Structure Anchor Bolts

Substation structure anchor bolts are embedded connection parts used to secure equipment supports, busbar structures, gantry frames, steel columns, and other supporting steel structures to concrete foundations.

They can be used for substation gantry structures, busbar supports, disconnect switch supports, circuit breaker supports, equipment platforms, control building steel columns, and outdoor electrical equipment foundations.

Different locations inside one substation may carry different structural and equipment loads. For this reason, the thread diameter, embedment length, exposed thread length, and anchor end are configured according to the specific foundation and steel base plate.

Each bolt group can be identified and packed according to the installation area, foundation number, or structural type. This helps keep bolts, nuts, washers, and anchor plates matched with the corresponding construction drawings.

Thread sizes range from M20 to M64. Total length can be produced from 400 to 2500 mm.

Strength classes include grade 4.8, grade 5.8, and grade 8.8. ASTM F1554 Grade 36 or Grade 55 can also be used according to the project requirements.

Available anchoring forms include straight rods with anchor plates, L-shaped bolts, J-shaped bolts, and structures used together with embedded sleeves.

Surface treatment options include plain finish, rust-preventive oil, hot-dip galvanizing, or a project-specified corrosion protection system. Outdoor substation bolts can receive hot-dip galvanizing, while embedded and exposed sections may use different protection configurations according to the technical documents.

Shandong Hongtaiyuan Electric Power Technology Co., Ltd. manufactures transmission towers, steel poles, communication towers, substation support structures, and matching anchor bolts.

The bolts can be supplied together with terminal frames, H-shaped poles, gantry structures, and other steel supports. The bolt diameter, template hole position, anchor plate dimensions, and accessory quantity are confirmed according to the foundation drawings.

OEM, ODM, and production from technical drawings or physical prototypes are supported. Different equipment foundations can be classified and produced by installation area or foundation number.

This coordinated production helps reduce the risk of mixing components for different support structures within the same substation project.

• The minimum order quantity is 1 ton. Paid samples can be arranged before mass production. Different bolt sizes and anchoring forms may be combined in the same order.

 

• Quality control includes processing self-inspection, semi-finished product sampling, and packaging inspection. Third-party inspection arranged by the customer is accepted.

 

• Production progress can be shared through photos or videos. Delivery time is determined according to bolt quantity, material grade, and matching component requirements.

• Export packaging receives secondary reinforcement to reduce thread damage, loose accessories, and mixed parts. The product includes a two-year warranty. Transport damage or missing components are reviewed and handled by the after-sales team.
