FAQ
What is the minimum bending radius of this drilling jumbo cable?
The bending radius is customized to the specific reeling application and cable outer diameter. As a general guideline, it can be designed to achieve a dynamic bending radius of 6 to 8 times the cable outer diameter. Please share your installation parameters so our engineers can confirm the optimal design.
Is this cable available with MSHA or other mining certifications?
Yes. Upon request, we manufacture cables in compliance with relevant international and regional standards, including MSHA, AS/NZS, and CAN/CSA, among others. Inquire with your specific certification needs.
What voltage rating does this cable support?
The standard design supports a rating of 0.6/1 kV. Higher voltage ratings can be engineered to suit your equipment’s requirements. We recommend verifying the required rating with your electrical specification before ordering.
What is the typical lead time and minimum order quantity (MOQ)?
Lead times and MOQ are project-specific and depend on the technical design and order volume. Contact our sales team with your target specifications and quantity, and we will provide a detailed quotation within 24 hours.
