Compression-type stringing clamp (for use with ACSR conductors)

Compression-type stringing clamp (for use with ACSR conductors)

for use with ACSR conductors

This device is used for the temporary connection of the tips of various electrical conductors during stringing. In addition, it is also used to put temporarily connected multiple conductors through a tensioner.
It has reliable retention force by being compressed. Along with this, the high stringing block passage performance makes the product well-suited for improving safety and reducing labor of stringing work.

Available
conductors
ACSR, HDCC, OPCW, GSW and AC conductors,
and other similar conductors
Basic
specifications
Tolerable stringing tension: 20% of UTS
Minimum tensile load: 60% of UTS

* UTS: Ultimate tensile strength of a conductor under the minimum tensile load

SR ring mounter

SR ring mounter

SR ring mounter

This machine automatically mounts snow accretion restrainer rings (SR rings), which are intended to prevent damage caused by snow to overhead transmission lines.
This machine has reduced size and weight to ease high-place work and alleviate any increase in conductor sag. In addition, its simple structure allows the machine to be easily used and operated. This machine can be operated via wireless remote from a tower or the ground.

Available conductors 38 to 100 mmm2
Gradability 25 degrees
Clearance between rings to be mounted Settable at any value
Power 24 V DC battery
Distance that can be travelled 1,200 m (each time the machine is fully charged)
Number of rings that can be mounted 4,000 (each time the machine is fully charged)
Operation Wireless Wireless output: specified low electric power (*1)
Reach from above the ground: approx. 80 m
Manual
Mass Approx. 25 kg

*1: Requires no qualifications or the filing of applications as prescribed in the Radio Act. As of 2011, the newest model of this product is under development. Please contact us for more details.

Cable checking machine capable of passing through a damper (Model NII) (of high vision specifications)

This device records images of the electrical conductor to a memory stick inserted into to a high vision camera in order to check the appearance (maximum recording time: 175 minutes (when recorded in PRO Duo 8GB of the AVC HD 5M (LP) type)).
This device uses a mirror to capture the images on a total of three planes of an electrical conductor (two upper planes and one lower plane) at one time.
On the left side of the image, a counter indicator is displayed to show the number of roller revolutions. The count is incremented by “1” when the roller has made five revolutions.
The device goes forward and backward and stops through wireless operation.
It can pass through a bolt-free damper or a damper with a breakaway bolt made by Viscas Corporation that is intended for use with ACSR stranded conductors of 330 mm2.

Suspended stringing block (Model KSA100)

Suspended stringing block (Model KSA100)

KSA100

This device is a ring-type suspended stringing block that is ideal for pulling off a pilot rope and electrical conductors during low-tension stringing. It consists of six rollers that are configured in a manner such that they form circular contours. This ensures contact of electrical conductors with the rollers at all times.

Model Model KSA100
Outline dimensions W 189mm x D 65mm x H 210mm
Mass 1.3kg
Acceptable conductor size St55mm2 to ACSR410mm2
Stringing capacity Vertical load: 150 kg
Stringing speed: 30 m/min.
Pilot rope φ 14 Kevlar rope

One-touch hooks (used mainly with principle and web members)

For web members

This hoisting accessory is used for the assembly of steel tower members. It can be removed by means of remote manipulation of the rope after the temporary tacking of bolts.
It has a mechanism that allows its removal only when it is under no loads. This ensures the safety of work.
As its removal does not involve worker’s climbing the tower, the crane’s standby time can be reduced.
