Helkama - a true specialist in 

shipboard cables 

Helkama is a company specializing in the manufacturing 

and development of shipboard cables. Our experience 

in manufacturing them goes back almost twenty years. 

The high technical quality has been achieved by continuous 

development work supported by our clients. 

With this catalog we are proud to introduce our most 

comprehensive range of shipboard cables. 

We have chosen to produce only halogen-free cables. 

They remarkably improve the fire safety of the ships by 

not emitting toxic burning fumes or thick smoke. 

In addition no corrosive gases damaging the ship and its 

equipment are emitted in case of a fire. Using the latest 

technology we also have been able to reduce cable weight 

and size to a minimum and still maintain quality, enabling 

easy installation. The halogen free range of cables includes 

both flame-retardant (IEC 60332-3A) and fire-resistant 

(IEC 60331) cables. Helkama shipboard cables are 

approved by all major classification societies. 

As a specialized, independent and optimum-sized 

company, focusing on service, we have been able to 

grow steadily by quickly responding to our customers’ 

needs. Our short delivery times, backed up by an 

extensive stock of cables, enable us to deliver punctually 

and keep our clients satisfied. This remains 

our goal for the future, too. 

In 1995, our 

quality system 

was certificated 

to ISO 9001 standards.

General information 

Insulation materials: 

The following designations are used for 

insulation materials in this catalog. All 

materials are halogen-free. 

XLPE stands for cross-linked polyethylene 

compound. It has excellent 

mechanical and electrical characteristics. 

HF85 stands for cross-linked polyolefine 

and combines very similar 

good characteristics with excellent 

flame-retardancy. PE/foamPE stands 

for a foamed polyethylene coated with 

a solid skin of polyethylene compound. 

This construction provides outstanding 

electrical features for data transmission. 

Sheathing materials: 

The designation SHF1 stands for 

thermoplastic compound. This material 

is halogen-free, highly flame-retardant 

and has low smoke emission. 

Definition of terms: 

Flame-retardant 

To be flame-retardant, the cables 

must withstand the test specified in 

IEC standard 60332-3 or IEC 60332-1. 

Flame-retardant cables do not propagate 

fire, and are self-extinguishing. 

IEC 60332-3 is the test for bunched 

wires and cables and has three categories 

A, B and C, defined by different 

limits for flammable material and 

burning times. Burning time describes 

how long the burner is directed towards 

the bunch of cables. The requirement 

for passing the test is that after the 

burner has been removed the cables 

must extinguish themselves. Burning 

may not occur more than 2.5 m from 

the burner as shown in the figure. 

Amount of 

Category burning Burning time 

material 

A 7 litres/m 40 min 

B 3,5 litres/m 40 min 

C 1,5 litres/m 20 min 

All Helkama cables 

comply with the most 

severe requirements 

of 

category A. 

Test on 

bunched 

cables 

IEC 60332-3 

Burning is 

allowed up 

to max. 2.5 

meters from 

the burner 

within 

specified time. 

IEC 60332-1 is the test for single insulated 

wire and cable. Test procedure and 

requirements according to the picture, 

below. 

50 mm 

475 550 600 

mm mm mm 

Min. 50 mm of the cable, measured from 

the upper support, must remain unburned 

after the specified time. 

Halogen-free 

Halogen-free refers to the absence 

of halogens, such as chlorine and 

fluorine, and is determined on 

the basis of halogen content and 

the acidity of gases of a cable. 

IEC 60754-1 determines the 

halogen content of the material. 

To meet the requirements as 

halogen-free the halogen content 

of the material may not exceed 

0,5 % or 5 mg/g. 

IEC 60754-2 determines the 

degree of acidity of gases evolved 

during combustion. The limit 

values are 4,3 for pH and 

10 mikroS for conductivity. 

Smoke emission 

Smoke emission refers to visibility 

in a fire. The greater the light transmittance, 

the better the visibility. 

When tested in accordance with 

IEC 61034-1 (test method) and 

IEC 61034-2 (test requirements) 

the smoke emission of a cable during 

fire must not exceed the following 

values. 

27m 3 cube 

smoke chamber 

1 cable min. 70 % light transmittance 

2–3 cables min. 60 % light transmittance 

> 3 cables min. 50 % light transmittance 

Fire-resistant 

To be classified as fire-resistant the cables must withstand the test specified 

in standard IEC 60331. The cables must operate for a minimum of 90 minutes 

while the burner is directed towards the cable as shown below. Helkama fireresistant 

cables are also flame-retardant.

Current rating at an ambient temperature of 45°C 

according to the standard IEC 60092-352 (cl.6) 

0,6/1 kV +85°C shipboard cables. 

For continuous service. Continuous service for a cable is to 

be considered as a current-carrying service (with constant 

load) having a duration longer than three times the thermal 

time constant of the cable, i.e. longer than the critical duration 

(see short time duty).
