Hanger ears

Model H for the Shinkansen

Hanger ears for the Shinkansen: Model H

Hanger ears of this model are used for the Shinkansen. A φ6 phosphor copper bar used as the hanger bar ensures higher reliability in strength and fatigue resistance. Model H hanger ears are ordinarily used with nylon messenger wire protection covers.

Main specifications of the product shown in the photograph
Model H
Tensile withstand load 1.47 kN (150 kgf) (for 3 minutes)
Slipping sideway withstand load 0.98 kN (100 kgf) (for 3 minutes)

Model A for narrow-gauge lines

Hanger ears for narrow-gauge lines: Model A

Model BLA hanger eras

Hanger ears of this model are used for narrow-gauge lines. A wedge driven in-between ear components from above produces the force that holds the contact wires. Model A hanger ears do not have any bolts. Accordingly, working on them does not require any special tools. Stainless steel flat plates with a 2 ☓ 15 mm cross section are used as the hanger bars.

Model A
Tensile withstand load 1.47 kN (150 kgf) (for 3 minutes)
Slipping sideway withstand load 0.98 kN (100 kgf) (for 3 minutes)

Model SC for narrow-gauge lines

在来線用 SC型

Hanger ears of this model are used for narrow-gauge lines. Their nail-clipper-shaped ears and levers produce the force that holds the contact wires. Model SC hanger ears do not have any bolts. Accordingly, working on them does not require any special tools. φ5 stainless steel bars are used as the hanger bars. Model SC hanger ears are lightweight and less prone to forming hard spots. They are also less affected by wind.

Main specifications of the product shown in the photograph
Model SC
Tensile withstand load 1.47 kN (150 kgf) (for 3 minutes)
Slipping sideway withstand load 0.98 kN (100 kgf) (for 3 minutes)

Epoxy hanger ear for narrow-gauge lines [insulation hanger wire]

Epoxy hanger ears for narrow-gauge lines (insulation hanger ears)

Hanger ears of this type are used to ensure the insulation of messenger wires at locations where messenger wires require insulation such as in station buildings and overbridges. A special, highly weather-resistant epoxy resin used for the hanger ears prevents degradation of insulator surfaces.

Main specifications of the product shown in the photograph
Model Epoxy insulation
Epoxy insulation 1.47 kN (150 kgf) (for 3 minutes)
Tensile withstand load 0.98 kN (100 kgf) (for 3 minutes)
Withstand voltage AC 10 kV (for 2 minutes, in a dry condition)

Model NHIG for feeder messenger wires [insulation hanger ear]

Hanger ears for use with feeder messenger wires for insulation: Model NHIG

Hanger ears of this model are used exclusively in places where two feeder messenger wires in a pair maintain a distance of 100 mm in DC overhead contact lines (1500 VDC). They are epoxy-resin insulation hanger ears, preventing feeding current from flowing between the messenger wire and the contact wire.

Main specifications of the product shown in the photograph
Model NHIG
Epoxy insulation 1.47 kN (150 kgf) (for 3 minutes)
Tensile withstand load 0.98 kN (100 kgf) (for 3 minutes)
Withstand voltage AC 10 kV (for 2 minutes, in a dry condition)
