Abstract

The utility model relates to a cable for electric appliance apparatuses in a distribution system and a control system and especially relates to a no-halogen low-smoke flame-retardant cable for a locomotive. The locomotive cable provided in the utility model comprises a conductor core (1). A conductor separating layer (2), insulating layers (3), a metal shielding layer (4), a shield separating layer (5) and an outer sheath layer (6) sequentially wrap the outer side of the conductor core (1) from the inside out. The conductor core (1) and the insulating layers (3) are separated by the conductor separating layer (2). The insulating layers (3) are wrapped by the metal shielding layer (4). The metal shielding layer (4) and the outer sheath layer (6) are separated by the shield separating layer (5). The outer sheath layer (6) wraps the shield separating layer (5) to form the cable. The cable which has a reasonable structural design and a stable quality can be widely applied in the electric appliance apparatus connecting field of the distribution system and the control system of rail transit vehicles. Furthermore, the cable has performances of oil resistance, high temperature resistance, humidity resistance, aging resistance and low toxicity, etc.

Description

Cable for locomotives

Technical field

The utility model relates to a kind of distribution system and control system electrical installation cable, relates in particular to a kind of LSOH anti-flaming retardant cable of locomotives.

Background technology

Locomotive is being born transporting cargo and personnel's task, thus when cable is used in design, even require cable in the situation that catch fire, also should be minimum people's harm is down to, so proposed the LSOH anti-flaming performance.And such cable environment for use is more abominable, has proposed again that cable is high temperature resistant, oil resistant, moisture-proof, the specific requirement such as ageing-resistant, causes general power cable can't replace its use.Main cause is that the fire retardant water absorbing properties in the LSOH anti-flaming material is more intense, and cable passes through anti-moisture test again, guarantee insulating performance of cable, this the contradiction of fire resistance and moisture resistance properties just occurred, so be difficult to satisfy simultaneously, this also is one of restriction cable material producer and cables manufacturing producer technological difficulties.

The utility model content

Technique effect of the present utility model can overcome defects, and a kind of cable for locomotives is provided, its fire resistance excellence and LSOH anti-flaming.

For achieving the above object, the utility model adopts following technical scheme: it comprises conductor cores, the conductor cores outside is wrapped up conductor isolation layer, insulating barrier, metal screen layer, shielding separator, external sheath layer from inside to outside successively, adopt the conductor isolation layer interval between conductor cores and the insulating barrier, insulating barrier is wrapped up by metal screen layer, adopt shielding separator interval between metal screen layer and the external sheath layer, external sheath layer parcel shielding separator forms cable.

Insulating barrier arranges two-layer, and its Insulation Material while extrusion molding by different irradiation materials and thickness forms.Metal screen layer adopts the tinned copper wire braiding, and count is not less than 80%.Oversheath adopts LSOH anti-flaming cross-linking radiation polyolefine material.

Conductor cores adopts stranded the forming of the zinc-plated soft copper single line of the 5th, six classes, plays to strengthen cable pliability and anti-copper oxidation; Wrapped one deck polyester belt is made separator outside conductor cores, plays and tightens conductor and keep the effect of conductor rounding; The outer irradiation crosslinked polyolefin insulating that will extrude simultaneously two-layer different materials and thickness of separator forms closely insulating barrier, and internal layer plays resistance effect, an outer fire-retardant and insulating effect; Insulating barrier adopts tinned copper wire braiding parcel outward, and count is not less than 80%; The outer wrapped one deck polyester belt of braid shielded is made separator, plays preventing from puncturing the sheath effect; Outside the shielding separator, extrude again one deck LSOH anti-flaming cross-linking radiation polyolefin external sheath layer and form cable.

The utility model Cable Construction Design is reasonable, and steady quality can be widely used in distribution system, the control system electrical installation connection area of rail traffic vehicles, has the performances such as oil resistant, high temperature resistant, moisture-proof, ageing-resistant, low toxicity.
