Manufacturing Process
From compound to shipment, the production steps and routine tests behind each cable length.
- 1
Compound preparation
EPR, CPE, PUR and silicone compounds are mixed and tested for hardness, tensile strength and elongation before use.
- 2
Conductor stranding
Tinned or bare copper is bunched and rope-stranded to Class 5/6 flexibility for trailing and reeling duty.
- 3
Insulation extrusion
Cores are extruded and continuously vulcanised; wall thickness and spark tests are recorded on every length.
- 4
Core assembly and screening
Cores, earth conductors, pilot and fibre-optic elements are laid up with the fillers and screens the type designation requires.
- 5
Inner and outer sheathing
Reinforced double-sheath constructions are extruded and cured for abrasion, oil and tear resistance.
- 6
Routine electrical tests
Conductor resistance, voltage withstand and insulation resistance tests at the levels set by the referenced standard.
- 7
Mechanical and ageing tests
Bending, tensile, hot-set, ozone and flame tests according to the referenced standard.
- 8
Marking, packing and shipment
Metre marking, drum packing and documentation for worldwide project delivery.
Cable Manufacturing Quality Control
Five-stage quality assurance from incoming copper to the packed drum.
- 01
Raw Material Inspection
Every batch of copper rod, rubber compound and reinforcing material is checked before it reaches the line.
- Copper: conductor resistance, elongation and surface condition on incoming rod and drawn wire
- EPR, CPE, PUR and silicone compounds: hardness, tensile strength, elongation and ageing samples from each mix
- 02
Manufacturing Process Control
Stranding, insulation extrusion, core assembly and sheathing run under recorded process parameters.
- Class 5/6 stranding with lay length and tension monitored for trailing and reeling flexibility
- Continuous-vulcanisation extrusion with wall thickness and spark tests logged on every length
- Operators sign off each stage before the cable moves to the next machine
- 03
Electrical Testing
Finished lengths go through the routine tests required by the referenced VDE, ICEA, IEC or NEK standard.
- Conductor resistance and insulation resistance on every length
- Voltage withstand test at the level set by the referenced standard
- Screen and pilot-core continuity checks for mining and reeling constructions
- 04
Mechanical and Ageing Tests
Samples from production are tested for the duty a mining, crane or submersible cable will actually see.
- Tensile strength and elongation of insulation and sheath before and after ageing
- Hot-set, ozone, oil-immersion and low-temperature bending tests
- Constant-temperature water bath for insulation resistance of submersible constructions
- 05
Flame Test and Final Inspection
Before packing, the cable is checked against the order and the flame-performance requirement of its standard.
- Single-cable vertical flame test to IEC 60332-1-2 where specified
- Metre marking, printing, drum length and appearance inspection
- Packing list with every shipment; test documents for the order confirmed at quotation

Quick answers about Marine & Offshore Cable from our engineers.
01What is LS3SU watertight shipboard cable?
LS3SU is a shielded multi-triad marine cable for shipboard power, control, communication and 400 Hz circuits. The common construction uses stranded copper conductors, cross-linked polyethylene insulation, a braided copper shield around each triad and a cross-linked polyolefin jacket. It is a construction designation rather than one size: triad count, conductor size, dimensions, voltage and qualification depend on the ordered design.
02How many triads and which conductor size does LS3SU have?
Common public references describe 3 to 44 shielded triads with 18 AWG stranded copper conductors, three conductors per triad, cabled with fillers and binder tape. Jacket thickness, outside diameter and weight vary with triad count and with LS3SU or LS3SUS construction; LS3SUS variants may add an overall shield. Confirm the exact size and rating on the project datasheet.
03Which standard applies to LS3SU cable?
The common public reference is MIL-C-24643/35. Confirm the exact revision, qualification, watertight test and approval scope for the supplied cable at RFQ stage. LS3SU is typically used in non-flexing shipboard service, so also state whether the installation involves any flexing, together with the routing and the fire and smoke requirements of the vessel.
04What is SIA GL cable and how is it specified?
SIA GL is a marine and shipboard cable designation for vessel electrical distribution and equipment connections. Its construction depends on conductor count, voltage, insulation system, sheath, armour or screen and classification requirements. TEBAOFLEX reviews the vessel specification and supplies a matching construction for marine routing, control or power duties, with project documentation for the governing shipboard specification and test standards.
05Where is SiF silicone cable used?
SiF is a flexible single-core wire with silicone rubber insulation for internal equipment wiring in elevated-temperature environments, such as heating appliances, luminaires, switchboards, control cabinets, motors and industrial machinery. The standard form has no separate outer sheath, so protect the insulation from sharp edges, excessive abrasion and incompatible chemicals. Common variants are low-voltage appliance wires; confirm the exact voltage, temperature range and standard.
06What should I send with a marine cable RFQ?
Send the core count, cross-section, voltage, length, installation method, environment, motion duty and required standards. For shipboard cables, add the governing shipboard specification, classification society, fire performance, smoke and halogen limits and water exposure. TEBAOFLEX will confirm the construction and provide the applicable datasheet; request test and certification documents for the exact model at RFQ stage.
