BM / BMTS / BMAI / BMAE / BSC insulating operating, telescopic and special sticks 3–420 kV

Country: Spain · Model: BM / BMTS / BMAI / BMAE / BSC

The BM, BMTS, BMAI, BMAE and BSC series insulating sticks for 3–420 kV are from 1.6 m long for single-section ones up to 10.30 m for extended telescopic ones. They are used to operate disconnectors and fuses, check for absence of voltage, apply and remove portable earths, discharge capacitors and rescue a casualty on overhead lines, in switchgear, at substations and in traction networks.

Description

The fibreglass tube of Ø 32–40 mm is closed with moisture-proof plugs and fitted with a hand guard, a handle and an interchangeable head. In a number of models the cavity is filled with polyurethane foam per IEC 60855, so moisture does not condense inside. The single-section operating BM and BME sticks with a universal head and hook are made in the BM-45, BM-66 and BM-90 versions of 1.6, 2.1 and 2.6 m for 45, 66 and 90 kV for indoor and outdoor installations in a dry environment. In the telescopic BMTS the sections lock automatically, the 3.4 kg BMTS-4/6 extends from 1.75 to 5.97 m and works up to 380 kV, and the seven-section BMTS-7/10.3 extends from 1.80 to 10.30 m for 420 kV. The two-section BMTS-15/45, BMTS-20/66 and BMTS-30 with length adjustment are intended for 45, 66 kV and above.

How to choose

The model is determined by operating voltage and environment. The sectional BMAI for dry environments are rated for 66 kV (BMAI-2, 2 m) and 110 kV (BMAI-2.5), and the reinforced BMAI-V made of Ø 38.4 mm tube for 132, 220 and 380 kV at lengths of 3, 4 and 5 m. In wet environments the BMAE-2 for 30 kV, the BMAE-2.5 for 66 kV and the multipurpose BSC-M and BSC-A per EN 50508 with polyurethane foam work, such as the BSC-M22 (2 m, 45 kV) and BSC-M32 (2.5 m, 66 kV). The ECBT earthing knives for NH fuses are installed with an insulated stick with an M10 thread.

FAQ

Which heads can be fitted to an insulating stick?

Universal (U), M10, bayonet (B) or hexagonal Hex-12 or Hex-22 (P/H). There are also adapters and attachments, including SM hooks and the SC33 saw for branches near overhead lines.

Which stick is needed to rescue a casualty?

BS rescue sticks with a hook are made for 3–66 kV in versions from BS-3 to BS-66.

What is used to discharge capacitors before work?

BDC and BDC-H discharge sticks with earthing, which also remove static charge.

What special sticks exist for fuses, fittings and wires?

The BEF-9000 works with fuses of Ø 30–90 mm, the BGT with a trigger mechanism grips and releases fittings on live lines, and the BCC cuts aluminium wires of 16–95 mm² and steel ones up to Ø 3 mm.

Which sticks exist for cleaning and for voltage detectors?

The PLD-1 stick is used for cleaning, and the PV-36 stick is intended for working with voltage detectors.
