220kV Power Transmission Pipe Tower

220kV power transmission pipe tower replaces the open lattice of angle steel members with a hollow, tapered polygonal steel shaft — usually 12-sided or 16-sided, formed by bending steel plate into a cone and welding the longitudinal seam. The result is a structure that is dramatically slimmer and visually lighter than a lattice tower of the same capacity.

Why does that matter? Because land is the most expensive component of any transmission line. The 220kV power transmission pipe tower needs a square base of 6–9 meters; a pipe tower of the same voltage needs a foundation barely larger than the shaft itself. Where right-of-way is narrow, land is costly, or communities object to "electricity pylons" in their view — the pipe tower is the design that keeps projects moving.

Structure and Materials of Transmission Pipe Tower

The shaft is fabricated from hot-rolled steel plate (Q345 / Q355) bent into a tapered polygon and welded with submerged arc welding along the seam. Sections are joined with slip-joint sleeves or flange connections, and cross-arms bolt onto the shaft at the top.

Shaft plate: Q345 / Q355, 6–30 mm thickness depending on height and load

Section connection: internal slip-joint (sleeve) or bolted flange rings

Cross-arms: lattice or tubular, single or double circuit configurations

Base: bolted base plate on anchor bolts, or direct-embedded shaft

Finish: hot-dip galvanized per ISO 1461, 85 µm minimum

Height: 25m – 60m standard; higher designs available on request

A key advantage of the pipe tower is its torsional stiffness. A lattice tower resists twisting through its bracing network; the closed polygonal shaft resists torsion inherently — which is why pipe towers handle unbalanced conductor loading and heavy angle turns so gracefully.

Key Features & Benefits

Land Footprint Cut by up to 70%

A 220kV power transmission pipe tower needs roughly one-third of the foundation area of an equivalent lattice tower. On a 50 km line, that difference can save thousands of square meters of compensated land — often the difference between project approval and deadlock.

Neighborhood-Friendly Profile

The slender shaft reads visually as a "pole" rather than a "pylon." Communities and planning authorities far more readily accept pipe towers along roads, through suburbs, and near residential zones. Several of our urban projects were approved precisely because the line spec called for pipe towers.

Superior Torsional Strength

The closed polygonal section gives the shaft high resistance to twisting loads. This makes pipe towers ideal for angle and terminal positions where unbalanced conductor tension would strain a lattice structure.

Faster Erection, Less Site Work

Fewer members mean faster assembly: a double-circuit 220kV power transmission pipe tower can be erected by a small crew with one crane in 1–2 days, versus 3–5 days for a lattice tower. Less site labor, less cranage, less weather exposure.

Clean, Low-Maintenance Design

No bracing network means no places for birds to nest, fewer climbing hazards, and easier future maintenance. The galvanized shaft surface is smooth and self-draining, shedding water and dirt efficiently.

Typical Applications

As a 220kV power transmission pipe tower manufacturer and supplier, MTtower supplies these towers in bulk at factory-direct pricing for:

220kV lines through agricultural land where footprint compensation is a major cost

Urban and suburban corridors with restricted right-of-way

Highway and railway adjacent routes where aesthetics matter

Substation entry and exit structures (terminal pipe towers)

Wind farm and PV plant 220kV collection and export lines

Upgrading existing 110kV corridors to 220kV without widening the right-of-way

FAQ

Q: When does a pipe tower make more sense than a lattice tower?

A: When land compensation is expensive, right-of-way is narrow, or aesthetics matter — urban areas, farmland, highways, and substation approaches. If land is cheap and the line runs through open country, a lattice tower is usually more economical. We can cost both options for your route.

Q: How is a 220kV power transmission pipe tower erected?

A: Sections are lifted by crane and joined by slip-joint or flange connections, bottom section first. Cross-arms are pre-assembled on the ground and lifted as one piece. A two-circuit pipe tower typically erects in 1–2 days with a 30–60 ton crane.

Q: Can pipe towers handle angle and terminal positions?

A: Yes — their torsional stiffness makes them particularly good at angle and terminal positions. Many projects use pipe towers for the whole line, including angles; for very heavy angles, we reinforce the shaft wall thickness.

Q: What is the zinc coating thickness?

A: Standard 85 µm minimum per ISO 1461. For coastal or industrial environments, we recommend 110–120 µm — available on request at modest cost increase.

Q: What is the lead time and MOQ?

A: MOQ for customized pipe towers: 1 set. Delivery for 30 sets: approximately 20 working days after deposit. Payment: 30% T/T deposit, balance before shipment.
