4. Mechanical & Safety Performance

Item

Specification

Min. bending radius

4 × overall thickness​ (flat short axis) for D<25 mm → ≈ 4×4.6 = 18.4 mm; maker rule: ≥4D of major axis (~28 mm) conservative

Flame retardant

Passes GB/T 18380.1 / IEC 60332-1​ (single vertical, self-extinguishing); ZC version = Class C bunch retardant per GB/T 19666

IP level

IP40 (bare) — sheath protects against minor abrasion, dust, humidity; not waterproof

Crush / abrasion

PVC/ST4 sheath resists minor foot traffic compression, skirting-board clamping, painter scraping

Smoke / halogen

Standard PVC emits smoke + HCl when burned; not LSZH​ — for low-smoke use WDZ-BVVB

Service life

≥ 30 years​ indoor at ≤70 °C conductor

Flexibility

Class 1 solid = stiff, for fixed wiring only; Class 2 stranded = slightly easier to dress, still not flexible like RVV

5. Product Performance Summary

BVVB 2×1.5 is the classic Chinese flat sheathed wire​ for surface-mounted fixed wiring. Its value proposition versus BV (single-core naked) and BVV (round sheathed):

  • Double protection in one piece​ — each core has PVC insulation + the whole assembly has a PVC sheath → resists moisture, dust, and minor mechanical knocks better than BV, without the bulky round profile of BVV.

  • Flat shape hugs walls​ — 4.6×7.3 mm cross-section sits flush under skirting boards, along tile edges, behind trunking lids; far neater than round BVV or conduit-run BV for retro-fit / visible runs.

  • 1.5 mm² is the lighting-and-small-socket sweet spot​ — 18 A free-air rating covers 220 V lighting circuits, switch drops, 1 A–10 A socket branches, appliance cords back to a fused spur.

  • Solid core = stable termination​ — Class 1 1/1.38 mm conductor clamps cleanly under screw terminals in switches, choc-boxes, and distribution boards; no strand splay if ferrule omitted (though ferrule still recommended).

  • Cost-effective​ — cheaper than armoured or LSZH cables; the default choice for non-emergency indoor exposed wiring.

Trade-off: not for direct burial​ (PVC sheath not rodent/soil rated), not for moving equipment​ (solid core fatigues), not fire-survival​ (standard PVC), not UV-stable​ for permanent outdoor sun exposure without conduit.

6. Application Scope

Primary uses

  • Residential surface wiring: living-room/bedroom lighting switches, ceiling rose feeds, skirting-board socket spurs

  • Retrofit / renovation​ where chasing walls is unwanted — run flat along cornices, door frames, under carpets (protected)

  • Small commercial fit-out​ lighting circuits, signage feeds, shop display lighting

  • Household appliances​ fixed connection: extractor hood, water heater switch drop, wall-mounted AC indoor unit power (low-current branch, not the 16 A socket itself)

  • Instrumentation, thermostats, doorbell transformers, CCTV camera 220 V feeds (low current)

  • Temporary site offices, exhibition booths, market stalls (indoor/under-canopy)

Typical projects:​ apartments & villas · office partitions · retail shops · school classrooms · hotel guest-room wiring · old-building rewire where conduit is impractical.

Not suitable for:​ direct burial · outdoor sun-exposed runs > few months · emergency/fire-alarm circuits (use NH-BV or WDZ-BYJ) · flexible appliance cords (use RVV) · 16 A+ socket radial circuits on long runs (use 2.5 mm² BV/BVVB) · 450/750 V industrial feeds (BV 450/750 is fine, but BVVB 2×1.5 is 300/500 V only).

7. Installation Notes (2×1.5 flat)

Item

Practice

Mounting

Clip to wall every 300–400 mm​ (plastic saddle/clip matching flat profile); not zip-tie on round surfaces

Bending

4× short-axis min (~18 mm); avoid creasing the flat edge — use gentle sweeps

Termination

Strip insulation 8–10 mm; solid core into screw terminal directly, or bootlace ferrule (DIN 46228 1.5 mm²) for panel use

Junction

Use choc-box or PVC junction box; never twist-and-tape in open air

Conduit?

Discouraged​ — flat shape scrapes sheath in round conduit; if conduit mandatory, use round BVV or single BV in conduit instead

Pre-energizing

500 V DC megger L-L, L-outer-sheath ≥ 1 MΩ; visual check sheath not nicked at clips

Low temp

Below 0 °C, warm cable before bending to avoid sheath cracking
