CH / CT / BH / BHM hydraulic heads 13–100 t, cutting heads and 700 bar pumps
Country: Spain · Model: CH / CT / BH / BHM
Hydraulic crimping heads of 13–100 t and cutting heads of 6–8 t run from a separate pump with a working pressure of 700 bar. The set is used for large-section cables, ACSR conductors on 110–220 kV overhead lines and for cutting LV, MV and HV cables when the force of a manual press is no longer enough.

Description
The head is connected to a foot, electric or battery pump by a 2 m high-pressure hose through a quick-release coupling, so the operator's hands stay away from the workpiece. The CH-13U with a hinged upper part and the C-type CH-13C, both 13 t, with HD13 dies crimp copper up to 400 mm², aluminium up to 300 mm² and bimetal up to 240 mm², and with CD13 dies they crimp crimpable clamps. The universal 20 t CH-20P makes hexagonal crimps on conductors of 10–630 mm², circular crimps for CRC, CRA and CRS clamps and deep stepped crimps for bimetal lugs up to 630 mm²; the CH-20P KIT includes dies for 300/400 mm² bimetal. The U-type CH-25 and CH-45 with pin locking and single-acting operation take copper up to 630 and 800 mm² respectively. The CH-60, CH-60A and CH-100/SA work with joint and tension clamps of overhead lines, and their HD100 dies accept copper and aluminium up to Ø 76 mm and steel up to Ø 36 mm. The CT-45 and CT-85 cutting heads also handle steel-aluminium conductors, and the KC-13/45 CT set combines both operations.
How to choose
The pump is selected to match the tonnage of the head. The EB-7 is designed only for 13 t heads, the foot-operated BH-700 with automatic double action needs no power supply, and the battery BHM-7 serves heads up to 100 t. The electro-hydraulic BGD-8 has a pressure gauge and automatic pressure switching and transmits data over Bluetooth and 4G. For sections up to 150 mm² without hydraulics, the SF-P150 manual crimping pliers are enough.

FAQ
Which hydraulic head should be used to crimp an 800 mm² copper lug?
Copper up to 800 mm² is handled by the U-type CH-45 of 45 t. The lighter 25 t CH-25 covers copper up to 630 mm² and is more convenient for work on overhead lines.
How many crimps does the BHM-7 battery pump make on one charge?
The 24 V 5.0 Ah battery lasts for about 150 crimps of 120 mm² copper lugs.
Are 70 MPa pumps suitable for heads rated for 700 bar?
Yes, 70 MPa and 700 bar are the same pressure, so the pumps of the series work with all CH and CT heads within their tonnage.
How can a cable that may be live up to 220 kV be cut remotely?
The KH-120LV and KH-140-VOLTCUT sets have an insulated 10 m hose and a remote control, so the operator stands far from the cutting point. The KH-140-VOLTCUT cuts Ø 140 mm with a force of 25 t.
