Power distribution centres

Bartec supplies damp-protected high-voltage three-phase air-transformers in pressure-resistant housing, for equipment power supply in underground mining.

Transformers come with a three or five-wave core, in a low-maintenance, corrugated-pipe boiler, with a junction box designed for both high voltage and low voltage applications. Capacities range from 400kVA to 2,000kVA.

High-voltage components can optionally be combined with a circuit breaker / earthing switch, or a circuit breaker / earthing switch and high voltage contactor. Low voltage components can be combined with a circuit breaker including one or two outgoing feeders.

The centres can also include switchgears / controlgears as draw-out unit, including six pluggable draw-out vacuum-contactors, fuses, protection and control technology, status displays and fault indications.

Mining frequency converters

Bartec also provides fire-damp protected, low-voltage mining frequency converters for speed-controlled drive engineering, for operations in armoured-face conveyors, belt conveyors and coilers.

This equipment can also be used as current source converters for 4Q-operation (drive and brake in both rotating directions) or PWM-inverters for 2Q-operation (drive in both rotating directions). The converters are executed as a compact station for de-central erection.

Converters come with a rated shaft power of between 250kW and 500kW, BdD type for 4Q operation; or between 90kW and 630kW, VSD type for 2Q operation, and have a nominal voltage of 3AC1kV or maximal 1,14kV.

Bartec converters include intrinsically safe PROFIBUS-DP-AM (ATEX mining) and FSK-modulation data transmission, and frequency or speed regulation and torque control, with or without speed feedback.

Three-phase motors for undergound mining machinery

Bartec manufactures low-voltage three-phase motors for underground mining applications, including models with a rated voltage of up to 3AC 1,140V, an air-cooled engine output of between 0,25kW and 400kW. Models with a rated voltage of up to 3AC 1,140V are also produced, with a water-cooled engine output of 90kW up to 630kW.

Bartec also manufactures these low-voltage motors as special motors for frequency converter operations of up to 630kW, fans and mining machines, as well as equipment with powerful drives of up to 800kW.

A high-voltage three-phase motor is also produced, with an engine output of between 300kW and 1,800kW, a rated voltage of 3AC 3, 3kV up to 6kV, and is air or water-cooled.

Mining automation, net protecting modules, components and accessories

Bartec also designs, manufactures and supplies the following components and accessories:

• Damp-protected mining controller with ETX-Board, CPU-Modul, communication modules
• IKS-mini control system for integration in explosion protected housings with PROFIBUS and CANopen-devices
• Decentral process modules (PROFIBUS AM-Ex, CANOpen Am-Ex) for connection with mining controllers or IKS-mini control systems
• Module power supplies (single and multiple-power)
• System components, interface components, signal former modules
• Terminal boxes with a steel-plate housing
• Polyester junction boxes for fibre optics
• Net-protecting components, including overload relays, isolation and SL-components, earth-leaking relays, PTC resistor trip relays
• I/O-systems including a PROFIBUS-device, Ethernet-network distributor with fibre optics net
• Network cameras with integrated web-server for network connection
• LED lights for longwall lights or head lamps

Bartec equipment is manufactured in compliance with QM – certificates DIN ISO 9001, ATEX 100a and IECEx.
