Marine rubber sheathed flexible cable CEFR-3 * 2.5

Marine rubber sheathed flexible cable CEFR-3 * 2.5

Usage: This product is suitable for transmitting electrical energy to various water structures such as river and sea vessels and offshore oil platforms.

Usage characteristics: The long-term allowable working temperature of the cable is 85 ℃, and the rated voltage Uo/U is 0.6/1KV. When laying, the small bending radius of the cable is as follows: the metal shielding armor type is 6 times the outer diameter of the cable. Non armored type, when the outer diameter is less than or equal to 25mm, it is 4 times the outer diameter of the cable, and when it is greater than 25mm, it is 6 times the outer diameter of the cable.
