RHEYFIRM®(RTS) (N)TSCGEWTOEUS

RHEYFIRM®(RTS) (N)TSCGEWTOEUS OFE is a breakthrough composite reeling cable engineered by Anhui Feichun Special Cable Co., Ltd. to meet the DIN VDE 0250-813 German industrial standard. It is the engineering world’s answer to a seemingly impossible challenge: simultaneously carrying massive amounts of high-voltage power (up to 30 kV) and zero-latency, high-bandwidth fiber optic data streams, while being relentlessly spooled onto a motorized drum under extreme mechanical tension and bending stress.

Modern container ports operate Ship-to-Shore (STS) cranes and massive gantry systems that demand unprecedented electrical power delivery. A typical STS trolley requires 18 kV to 30 kV of main power to lift 65-ton containers at speeds exceeding 600 meters per minute. This power must flow through a festoon cable system—a continuous loop of cable that unwinds and rewinds thousands of times per day as the trolley travels back and forth along the boom. Traditional round cables cannot solve this problem efficiently. A round medium voltage cable, rated for 18/30 kV, becomes rigid and difficult to bend. It occupies excessive space in the festoon track, requiring long parking lengths and increasing the footprint of the crane's electrical infrastructure. By contrast, a flat cable lays its massive phase cores side-by-side in a single plane, allowing for an incredibly tight bending radius—sometimes as small as 10 to 15 centimeters—while maintaining full electrical power delivery. This single geometric advantage reduces festoon track length by up to 40 percent, enabling faster crane acceleration and dramatically improving container terminal throughput.
