Q1: The main shaft has a diameter of 220mm and includes hydraulic lines; can the slip ring’s through-bore accommodate them?
A: With room to spare. JINPAT offers a wide range of standard bore diameters—from 100mm to 980mm—and supports custom non-standard specifications. The main shaft and cabling can pass directly through the bore, enabling coaxial mounting that utilizes every inch of available mechanical space.
Q2: Given the harsh conditions—including wind, sand, and heavy rain—is an IP65 protection rating sufficient?
A: It meets the standards completely. Our products have been rigorously tested by CNAS-accredited laboratories. Featuring aging-resistant sealing rings paired with a 316 stainless steel housing, the units withstood 500 hours of salt spray testing without any ingress. The real-world operational track records of CNOOC and CNPC in extreme offshore and desert environments serve as the ultimate proof of their durability.
Q3: Factory-prewired leads can be too rigid; can I handle the wiring myself on-site?
A: That is precisely one of our key features. The interior of the slip ring is pre-fitted with copper bolt connection posts or terminal blocks. Based on your specific on-site requirements, you can use your own cables—cutting, crimping, and securing them directly—offering exceptional flexibility during installation.
Q4: Since the slip ring is mounted dozens of meters high, what can be done to simplify inspection and maintenance?
A: No extensive disassembly is required. JINPAT has designed a transparent inspection window that allows you to assess carbon brush wear simply by shining a flashlight through it. Should replacement be necessary, you need only unscrew the maintenance port cover—a task that can be performed by a single person, reducing maintenance time from a full morning down to just fifteen minutes.
Q5: Does the large through-bore design compromise the slip ring’s current-carrying capacity?
A: Not in the slightest. Current-carrying capacity is determined by the contact ring area and contact design; JINPAT employs a multi-contact parallel connection technology to ensure robust performance. For instance, our 980mm large-bore models can still stably transmit currents exceeding 540A, successfully combining spacious internal clearance with powerful electrical transmission capabilities.
Q6: JINPAT pricing is higher than that of standard brands—is it worth it?
A: Let’s do the math: unplanned downtime on a drilling platform can cost as much as 200,000 RMB per hour. Through its high reliability and rapid maintenance capabilities, JINPAT minimizes the risk of failure. For most users, the price difference is recouped within just six months solely through the reduction in downtime.
