Explanation of Model Codes for Marine Cables
The cable model codes for Chinese marine cables is an "identity identifier" that follows specific rules. Model naming is composed of letters and numbers in the order of cable structure from inside to outside. Please refer to the table below for detailed code explanations, covering the most common series, materials, and structures.
Overview
Full analysis of marine cable model codes:
Code position | Code | Explanation | Remark |
Series/Application (1st and 2nd positions) | C | Marine/Shipboard power cable | The basic series code |
CK | Marine/Shipboard control cable | For control system | |
CH | Marine/Shipboard communication/instrument cable | For communication/instrument system | |
CB | Marine/Shipboard wire | Used for lighting, sockets | |
Insulation | E | EPR | Soft and flexible |
J | XLPE | Main used insulation materials | |
V | PVC | Average performance, gradually being replaced | |
X | Natural styrene butadiene rubber | rarely used | |
Inner Sheath | F | Polychloroprene rubber | Good oil resistance and weather resistance |
H | Chlorosulphonated polyethylene rubber | Excellent weather resistance and chemical resistance | |
V | Polyvinyl chloride (PVC) | ||
PF | Thermoplastic polyolefin | Halogen-free, low-smoke, environmentally friendly materials | |
PJ | Cross linked polyolefin | Halogen-free, low-smoke, and cross-linked, with better performance but harder than PF | |
Armor (the 1st Number) | 8 | Tinned copper wire braided | Mainly used for electromagnetic shielding |
9 | Galvanized steel wire braided | Better mechanical protection, higher tensile strength | |
Outer sheath (the 2nd Number) | 0 | No outer sheath | |
2 | Polyvinyl chloride (PVC) | ||
5 | Cross linked polyolefin | Similar to PJ, halogen-free, low-smoke | |
6 | Thermoplastic polyolefin | Similar to PF, halogen-free, low-smoke |
Fire performance:
This section is usually added at the end of the cable model, separated by a slash, to indicate the flame-retardant and fire-resistant characteristics of the cable.
Flame retardant properties:
D: Single vertical flame retardant (DA, DC).
S: Bundled vertical flame retardant (SA, SC).
Halogen/smoke (often combined with D/S, such as SA, DC, NC):
A: Smoke, Acid and Toxic (containing halogen).
C: Halogen-free, low smoke, and low toxicity.
Fire resistance characteristics:
N: Fire resistant. Often combined with the above, such as NC representing halogen-free low smoke bundled flame retardant and fire-resistant.
A complete model usually has the following code sequence: application-insulation-inner sheath- armor-outer sheath-combustion characteristics.
Example: C-J-PJ-85/SC
C: Marine power cable
J: Cross linked polyethylene(XLPE) insulation
PJ: Cross linked polyolefin inner sheath
85:8 (copper wire braided armor)+5 (cross-linked polyolefin outer sheath).
SC: Halogen free low smoke bundle flame retardant
