Professional China Optical Ground Wire - semi-conductive water blocking tape – Siber Detail:

SIBER water blocking tapes have an excellent swelling property.When water enters into a cable protected by water blocking tape,the super absorbent powder within the tape instantly forms a water blocking gel,that prevents further and more costly damage to the cable.

SIBER water blocking tapes are available not only semi-conductive but also non-conductive,PET laminated versions to suit diverse cable applications.

Specification of Non-Conductive Water Blocking Tape

TYPE Thickness (mm) Weight(g/㎡) Swelling Speed(mm/1st min) Swelling Height (mm/3 min) Tensile Strength(N/cm) Surface Resistance (Ω) Volumn Resistance(Ω.cm)
BZD-25 0.25 80+10 6 12 ≥25 <1500 <106
BZD-30 0.30 100+10 10 14 ≥40 <1500 <106
BZD-40 0.40 130+12 12 16 ≥40 <1500 <106
BZD-50 0.50 150+15 14 18 ≥40 <1500 <106

Application: Be used for cushion and water blocking inside metal jacket of super high voltage power cable.

It has low surface resistance, low volume resistance, high tensile strength, good temperature resistance and good anti-adhesive.

With the advantages:semi-conductive black carbon doesn’t fade and take off easily, good semi-conductive performance, cushion elasticity durability, especially the surface bonding of water absorbent powder with semi-conductive non-woven fabric is very strong, water swelling performance is excellent. We have full set of production equipment from raw material to finished products.

The products are widely applied in the top 10 cable factories in China and famous cable factories in the world, like: Prysmian, Nexans, LS, Hayat Power Cable, Procab, Aberdare Cables, CBI Electric, Hengtong, Baosheng, ZTT, Shangshang, Far East and Jiangnan.
