Frequently Asked Questions

How do I request electrical and energy equipment?

Use the quotation form on this page. Include the equipment type, quantity and application, and attach the project documents you have — each equipment guide lists the information that matters for that equipment.

Which documents should I send?

Where applicable: the single-line diagram, load schedule, BOQ, equipment or panel schedules and the consultant specification. For existing equipment, nameplate photos and the model also help.

Can I include several items in one request?

Yes. You can include several electrical and energy equipment requirements in one quotation request.

Can GOLTENS provide a replacement for existing equipment?

For generator sets, transfer switches, UPS, voltage stabilizers, battery chargers and rectifiers, sub-distribution boards and industrial or high-mast lighting, send the nameplate, photos, the available technical information and the quantity. GOLTENS reviews the available equipment information and can source a matching or technically suitable alternative for quotation. Final equivalence and suitability should be confirmed by the customer's engineering team.

Is the electrical system design part of the quotation?

No. Equipment is quoted against the documents, information and specification you provide; the system design and final selection remain with your engineering team or consultant.

What if I don't have complete technical information?

Send what you have. The minimum is the equipment type, quantity and application; missing details can be clarified during quotation.

Can you supply equipment not listed on this page?

The guides cover common electrical distribution, standby power, lighting, solar and storage equipment. Additional equipment can be reviewed according to your requirement — send the details through the quotation form.

What is the lead time?

Lead time depends on the equipment and its configuration. Configuration and availability are confirmed during quotation, so we state the lead time in each quotation rather than quote a single blanket figure.
