The Most Complete Solution in Remote-
controlled Disconnectors

  • We deliver comprehensive remote control solutions tailored to the specific requirements of each CFE distribution area, whether for submersible or pedestal-type disconnectors.
  • In the medium voltage disconnector sources we offer the option of obtaining the presence of voltage through digital sensors that are placed in the T-bodies of the disconnector or an analog voltage measurement with capacitive sensors inside the bushings.
  • We offer current measurement either on the loads or, if the client requires it, on all paths.
  • All our remote-controlled disconnector proposals include a self-powered transformer (TP or potential transformer) to power the entire control, protection, and communications panel.
  • Submersible control cabinet option.
  • If you require a split bus, we offer the option of motorized or manual operation.
  • We offer automatic fault isolation packages for university campuses, shopping malls, hospitals, resorts, and other residential, commercial, and industrial complexes.

Medium Voltage Disconnectors With LAPEM Certification and We Deliver SIGLA03

  • Whether you need a medium-voltage service disconnector or a medium-voltage underground disconnector, our equipment has the following certifications:
  • Pedestal disconnector with SF6 (Sulfur Hexafluoride) gas insulation according to CFE VM000-51 standard .
  • Submersible disconnector with SF6 (Sulfur Hexafluoride) insulation according to CFE VM000-68 standard .
  • Pedestal disconnector or submersible disconnector with solid insulation according to CFE standard VM000-74 .

We Optionally Offer Configuration and Commissioning for Distribution Disconnectors.

  • Wiring the control, checking operations with the control in local mode
  • In local mode, we verify the correct operation of alarms and controls
  • Protection relay configuration with the parameters delivered with the protection coordination study
  • Corroboration tests of Time-Current curves on the load sides (electrical switch).
  • DNP mapping, where we indicate the points for the SCADA or CFE master.
  • Configuration of the communication DEI (SCADA radio, fiber optic modem, GPRS, Wi-Fi, Bluetooth or whatever equipment has been supplied).
  • We provide support for remote verification of the correct operation of alarms and controls.
  • We always bear in mind the importance of maintaining the safety of electrical installations and equipment in the event of electrical, mechanical, climatic, and environmental contingencies that could affect them, according to a note in the Official Gazette of the Federation. We also follow NOM-029-STPS-2011, which establishes the safety measures that must be adopted in electrical substations, including obtaining authorization to perform work and using the necessary personal protective equipment.
  • With our service, your G&W disconnector maintains its factory warranty.

We Have a Design for ELECTRIC ARC (Arc Flash) in a Medium Voltage Disconnector

  • To maximize operator safety, G&W has created a special design where the electrical disconnector tank can contain an internal electric arc fault of 25 kA for 0.25 seconds in SF6 according to IEC62271-200 High-voltage switchgear and control gear — Part 200: AC metal-enclosed switchgear and control gear for rated voltages above 1 kV and up to and including 52 kV.
  • The tank is capable of withstanding a maximum pressure of 170 psi without rupturing. This ability to contain this pressure surge makes this tank ideal for pedestal or vault applications where venting is not required.
  • These switches are tested according to IEEE standards C37.72, C37.74, C37.60, and IEC265, applying to the TNI and GNI disconnector models.
  • The G&W Electric TNI is a two-pronged disconnector with the operating mechanism on one side and the connection bushings on the other. 630 A on the source side and main bus bar paths. 630 A continuous on the protected load-side paths.
  • The G&W Electric GNI is a single-sided disconnector with the operating mechanism and connection bushings on one side. 630 A or 900 A on the source side and main bus bar paths. 630 A continuous on the protected load-side paths.
