Description

Transformer Cross Arm is used as the support beam for pole-mounted distribution transformer platforms. It fits the transformer base, double-pole spacing, braces, and M12 or M16 8.8 grade hot-dip galvanized bolts. The useful point is that the beam length, hole position, and brace layout can be made as one platform set, so the site team can lift and assemble the transformer support without cutting the galvanized steel.

Product Advantages

1) Transformer Cross Arm uses channel steel with fixed section data, so the drawing can match transformer weight and pole distance before production.

2) The 2.5 m and 2.85 m beam lengths follow common double-pole spacing, which reduces cutting at the pole site.

3) Bolts, braces, plates, and beam marks can be packed by platform set for easier lifting and installation.

Main Applications

Used for distribution transformer platforms, pole-mounted equipment supports, and power distribution reconstruction projects.

Suitable for 0.4 kV and 10 kV related pole platform hardware when drawings are confirmed.

Quality Control

Hole position is checked against the transformer platform drawing before galvanizing and again before packing.

After hot-dip galvanizing, the surface is inspected for bare steel, sharp zinc lumps, and blocked bolt holes.

Customization Service

We can produce by drawing, sample, or project size list when standard catalogue sizes do not match the site.

Before production, the order should confirm material grade, surface finish, holes, length, and accessory quantity.

FAQ

Q: What beam size is normally used?

A: 10# channel steel 100×48×5.3 mm is used for common platforms. 12# channel steel 120×53×5.5 mm can be selected for heavier or stronger wind conditions.

Q: What data should be sent before production?

A: Send pole spacing, platform width, transformer size, bolt hole position, and required beam length.

Q: Can bolts be shipped with the beams?

A: Yes. Transformer Cross Arm can be packed with M12 or M16 8.8 grade hot-dip galvanized bolts, nuts, and washers by platform set.
